+## TOML parser and encoder for Go with reflection
+
+TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
+reflection interface similar to Go's standard library `json` and `xml` 
+packages. This package also supports the `encoding.TextUnmarshaler` and
+`encoding.TextMarshaler` interfaces so that you can define custom data 
+representations. (There is an example of this below.)
+
+Spec: https://github.com/mojombo/toml
+
+Compatible with TOML version
+[v0.2.0](https://github.com/mojombo/toml/blob/master/versions/toml-v0.2.0.md)
+
+Documentation: http://godoc.org/github.com/BurntSushi/toml
+
+Installation:
+
+```bash
+go get github.com/BurntSushi/toml
+```
+
+Try the toml validator:
+
+```bash
+go get github.com/BurntSushi/toml/cmd/tomlv
+tomlv some-toml-file.toml
+```
+
+[![Build status](https://api.travis-ci.org/BurntSushi/toml.png)](https://travis-ci.org/BurntSushi/toml)
+
+
+### Testing
+
+This package passes all tests in
+[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
+and the encoder.
+
+### Examples
+
+This package works similarly to how the Go standard library handles `XML`
+and `JSON`. Namely, data is loaded into Go values via reflection.
+
+For the simplest example, consider some TOML file as just a list of keys
+and values:
+
+```toml
+Age = 25
+Cats = [ "Cauchy", "Plato" ]
+Pi = 3.14
+Perfection = [ 6, 28, 496, 8128 ]
+DOB = 1987-07-05T05:45:00Z
+```
+
+Which could be defined in Go as:
+
+```go
+type Config struct {
+  Age int
+  Cats []string
+  Pi float64
+  Perfection []int
+  DOB time.Time // requires `import time`
+}
+```
+
+And then decoded with:
+
+```go
+var conf Config
+if _, err := toml.Decode(tomlData, &conf); err != nil {
+  // handle error
+}
+```
+
+You can also use struct tags if your struct field name doesn't map to a TOML
+key value directly:
+
+```toml
+some_key_NAME = "wat"
+```
+
+```go
+type TOML struct {
+  ObscureKey string `toml:"some_key_NAME"`
+}
+```
+
+### Using the `encoding.TextUnmarshaler` interface
+
+Here's an example that automatically parses duration strings into 
+`time.Duration` values:
+
+```toml
+[[song]]
+name = "Thunder Road"
+duration = "4m49s"
+
+[[song]]
+name = "Stairway to Heaven"
+duration = "8m03s"
+```
+
+Which can be decoded with:
+
+```go
+type song struct {
+  Name     string
+  Duration duration
+}
+type songs struct {
+  Song []song
+}
+var favorites songs
+if _, err := Decode(blob, &favorites); err != nil {
+  log.Fatal(err)
+}
+
+for _, s := range favorites.Song {
+  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
+}
+```
+
+And you'll also need a `duration` type that satisfies the 
+`encoding.TextUnmarshaler` interface:
+
+```go
+type duration struct {
+	time.Duration
+}
+
+func (d *duration) UnmarshalText(text []byte) error {
+	var err error
+	d.Duration, err = time.ParseDuration(string(text))
+	return err
+}
+```
+
+### More complex usage
+
+Here's an example of how to load the example from the official spec page:
+
+```toml
+# This is a TOML document. Boom.
+
+title = "TOML Example"
+
+[owner]
+name = "Tom Preston-Werner"
+organization = "GitHub"
+bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
+dob = 1979-05-27T07:32:00Z # First class dates? Why not?
+
+[database]
+server = "192.168.1.1"
+ports = [ 8001, 8001, 8002 ]
+connection_max = 5000
+enabled = true
+
+[servers]
+
+  # You can indent as you please. Tabs or spaces. TOML don't care.
+  [servers.alpha]
+  ip = "10.0.0.1"
+  dc = "eqdc10"
+
+  [servers.beta]
+  ip = "10.0.0.2"
+  dc = "eqdc10"
+
+[clients]
+data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
+
+# Line breaks are OK when inside arrays
+hosts = [
+  "alpha",
+  "omega"
+]
+```
+
+And the corresponding Go types are:
+
+```go
+type tomlConfig struct {
+	Title string
+	Owner ownerInfo
+	DB database `toml:"database"`
+	Servers map[string]server
+	Clients clients
+}
+
+type ownerInfo struct {
+	Name string
+	Org string `toml:"organization"`
+	Bio string
+	DOB time.Time
+}
+
+type database struct {
+	Server string
+	Ports []int
+	ConnMax int `toml:"connection_max"`
+	Enabled bool
+}
+
+type server struct {
+	IP string
+	DC string
+}
+
+type clients struct {
+	Data [][]interface{}
+	Hosts []string
+}
+```
+
+Note that a case insensitive match will be tried if an exact match can't be
+found.
+
+A working example of the above can be found in `_examples/example.{go,toml}`.

+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/mojombo/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.

+
+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the

+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent

+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section

+
+## Installation
+Simple install the package to your [$GOPATH](http://code.google.com/p/go-wiki/wiki/GOPATH "GOPATH") with the [go tool](http://golang.org/cmd/go/ "go command") from shell:
+```bash
+$ go get github.com/go-sql-driver/mysql
+```
+Make sure [Git is installed](http://git-scm.com/downloads) on your machine and in your system's `PATH`.
+
+## Usage
+_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](http://golang.org/pkg/database/sql) API then.
+
+Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name)  as `dataSourceName`:
+```go
+import "database/sql"
+import _ "github.com/go-sql-driver/mysql"
+
+db, e := sql.Open("mysql", "user:password@/dbname?charset=utf8")
+```
+
+[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
+
+
+### DSN (Data Source Name)
+
+The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
+```
+[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
+```
+
+A DSN in its fullest form:
+```
+username:password@protocol(address)/dbname?param=value
+```
+
+Except of the databasename, all values are optional. So the minimal DSN is:
+```
+/dbname
+```
+
+If you do not want to preselect a database, leave `dbname` empty:
+```
+/
+```
+
+#### Password
+Passwords can consist of any character. Escaping is **not** necessary.
+
+#### Protocol
+See [net.Dial](http://golang.org/pkg/net/#Dial) for more information which networks are available.
+In general you should use an Unix domain socket if available and TCP otherwise for best performance.
+
+#### Address
+For TCP and UDP networks, addresses have the form `host:port`.
+If `host` is a literal IPv6 address, it must be enclosed in square brackets.
+The functions [net.JoinHostPort](http://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](http://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
+
+For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
+
+#### Parameters
+***Parameters are case-sensitive!***
+
+Possible Parameters are:
+  * `timeout`: **Driver** side connection timeout. The value must be a string of decimal numbers, each with optional fraction and a unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout).
+  * `charset`: Sets the charset used for client-server interaction ("SET NAMES `value`"). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
+  * `allowAllFiles`: `allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files. *Might be insecure!*
+  * `parseTime`: `parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
+  * `loc`: Sets the location for time.Time values (when using `parseTime=true`). The default is `UTC`. *"Local"* sets the system's location. See [time.LoadLocation](http://golang.org/pkg/time/#LoadLocation) for details.
+  * `strict`: Enable strict mode. MySQL warnings are treated as errors.
+
+All other parameters are interpreted as system variables:
+  * `autocommit`: *"SET autocommit=`value`"*
+  * `time_zone`: *"SET time_zone=`value`"*
+  * `tx_isolation`: *"SET [tx_isolation](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation)=`value`"*
+  * `param`: *"SET `param`=`value`"*
+
+#### Examples
+```
+user@unix(/path/to/socket)/dbname
+```
+
+```
+user:password@tcp(localhost:5555)/dbname?charset=utf8&autocommit=true
+```
+
+```
+user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?charset=utf8mb4,utf8
+```
+
+```
+user:password@/dbname
+```
+
+No Database preselected:
+```
+user:password@/
+```
+
+### `LOAD DATA LOCAL INFILE` support
+For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
+```go
+import "github.com/go-sql-driver/mysql"
+```
+
+Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` (might be insecure).
+
+To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then.
+
+See also the [godoc of Go-MySQL-Driver](http://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation")
+
+### `time.Time` support
+The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm.
+
+However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](http://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
+
+**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
+
+Alternatively you can use the [`NullTime`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
+
+
+
+## Testing / Development
+To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
+
+Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.
+If you want to contribute, you can work on an [open issue](https://github.com/go-sql-driver/mysql/issues?state=open) or review a [pull request](https://github.com/go-sql-driver/mysql/pulls).
+
+Code changes must be proposed via a Pull Request and must be reviewed. Only *LGTM*-ed (" *Looks good to me* ") code may be committed to the master branch.

+[![Build Status](https://drone.io/github.com/jmoiron/sqlx/status.png)](https://drone.io/github.com/jmoiron/sqlx/latest) [![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/jmoiron/sqlx) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/jmoiron/sqlx/master/LICENSE)
+
+sqlx is a library which provides a set of extensions on go's standard
+`database/sql` library.  The sqlx versions of `sql.DB`, `sql.TX`, `sql.Stmt`,
+et al. all leave the underlying interfaces untouched, so that their interfaces
+are a superset on the standard ones.  This makes it relatively painless to
+integrate existing codebases using database/sql with sqlx.
+
+Major additional concepts are:
+
+* Marshal rows into structs (with embedded struct support), maps, and slices
+* Named parameter support including prepared statements
+* `Get` and `Select` to go quickly from query to struct/slice
+* `LoadFile` for executing statements from a file
+
+There is now some [fairly comprehensive documentation](http://jmoiron.github.io/sqlx/) for sqlx.
+You can also read the usage below for a quick sample on how sqlx works, or check out the [API
+documentation on godoc](http://godoc.org/github.com/jmoiron/sqlx).
+
+## Recent Changes
+
+The ability to use basic types as Select and Get destinations was added.  This
+is only valid when there is one column in the result set, and both functions
+return an error if this isn't the case.  This allows for much simpler patterns
+of access for single column results:
+
+```go
+var count int
+err := db.Get(&count, "SELECT count(*) FROM person;")
+
+var names []string
+err := db.Select(&names, "SELECT name FROM person;")
+```
+
+See the note on Scannability at the bottom of this README for some more info.
+
+### Backwards Compatibility
+
+There is no Go1-like promise of absolute stability, but I take the issue
+seriously and will maintain the library in a compatible state unless vital
+bugs prevent me from doing so.  Since [#59](https://github.com/jmoiron/sqlx/issues/59) and [#60](https://github.com/jmoiron/sqlx/issues/60) necessitated
+breaking behavior, a wider API cleanup was done at the time of fixing.
+
+## install
+
+    go get github.com/jmoiron/sqlx
+
+## issues
+
+Row headers can be ambiguous (`SELECT 1 AS a, 2 AS a`), and the result of
+`Columns()` can have duplicate names on queries like:
+
+```sql
+SELECT a.id, a.name, b.id, b.name FROM foos AS a JOIN foos AS b ON a.parent = b.id;
+```
+
+making a struct or map destination ambiguous.  Use `AS` in your queries
+to give rows distinct names, `rows.Scan` to scan them manually, or 
+`SliceScan` to get a slice of results.
+
+## usage
+
+Below is an example which shows some common use cases for sqlx.  Check 
+[sqlx_test.go](https://github.com/jmoiron/sqlx/blob/master/sqlx_test.go) for more
+usage.  
+
+
+```go
+package main
+
+import (

+)
+
+var schema = `

+    city text NULL,
+    telcode integer
+)`

+
+    // Named queries, using `:name` as the bindvar.  Automatic bindvar support
+    // which takes into account the dbtype based on the driverName on sqlx.Open/Connect
+    _, err = db.NamedExec(`INSERT INTO person (first_name,last_name,email) VALUES (:first,:last,:email)`, 
+        map[string]interface{}{
+            "first": "Bin",
+            "last": "Smuth",
+            "email": "bensmith@allblacks.nz",
+    })
+
+    // Selects Mr. Smith from the database
+    rows, err = db.NamedQuery(`SELECT * FROM person WHERE first_name=:fn`, map[string]interface{}{"fn": "Bin"})
+
+    // Named queries can also use structs.  Their bind names follow the same rules
+    // as the name -> db mapping, so struct fields are lowercased and the `db` tag
+    // is taken into consideration.
+    rows, err = db.NamedQuery(`SELECT * FROM person WHERE first_name=:first_name`, jason)
+}
+```
+
+## Scannability
+
+Get and Select are able to take base types, so the following is now possible:
+
+```go
+var name string
+db.Get(&name, "SELECT first_name FROM person WHERE id=$1", 10)
+
+var ids []int64
+db.Select(&ids, "SELECT id FROM person LIMIT 20;")
+```
+
+This can get complicated with destination types which are structs, like `sql.NullString`.  Because of this, straightforward rules for *scannability* had to be developed.  Iff something is "Scannable", then it is used directly in `rows.Scan`;  if it's not, then the standard sqlx struct rules apply.
+
+Something is scannable if any of the following are true:
+
+* It is not a struct, ie. `reflect.ValueOf(v).Kind() != reflect.Struct`
+* It implements the `sql.Scanner` interface
+* It has no exported fields (eg. `time.Time`)
+
+## embedded structs
+
+Scan targets obey Go attribute rules directly, including nested embedded structs.  Older versions of sqlx would attempt to also descend into non-embedded structs, but this is no longer supported.
+
+Go makes *accessing* '[ambiguous selectors](http://play.golang.org/p/MGRxdjLaUc)' a compile time error, defining structs with ambiguous selectors is legal.  Sqlx will decide which field to use on a struct based on a breadth first search of the struct and any structs it embeds, as specified by the order of the fields as accessible by `reflect`, which generally means in source-order.  This means that sqlx chooses the outer-most, top-most matching name for targets, even when the selector might technically be ambiguous.
+
+## scan safety
+
+By default, scanning into structs requires the structs to have fields for all of the
+columns in the query.  This was done for a few reasons:
+
+* A mistake in naming during development could lead you to believe that data is
+  being written to a field when actually it can't be found and it is being dropped
+* This behavior mirrors the behavior of the Go compiler with respect to unused
+  variables
+* Selecting more data than you need is wasteful (more data on the wire, more time
+  marshalling, etc)
+
+Unlike Marshallers in the stdlib, the programmer scanning an sql result into a struct
+will generally have a full understanding of what the underlying data model is *and*
+full control over the SQL statement.
+
+Despite this, there are use cases where it's convenient to be able to ignore unknown
+columns.  In most of these cases, you might be better off with `ScanSlice`, but where
+you want to still use structs, there is now the `Unsafe` method.  Its usage is most
+simply shown in an example:
+
+```go
+    db, err := sqlx.Connect("postgres", "user=foo dbname=bar sslmode=disable")
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    type Person {
+        Name string
+    }
+    var p Person
+
+    // This fails, because there is no destination for location in Person
+    err = db.Get(&p, "SELECT name, location FROM person LIMIT 1")
+    
+    udb := db.Unsafe()
+    
+    // This succeeds and just sets `Name` in the p struct
+    err = udb.Get(&p, "SELECT name, location FROM person LIMIT 1")
+```
+
+The `Unsafe` method is implemented on `Tx`, `DB`, and `Stmt`.  When you use an unsafe
+`Tx` or `DB` to create a new `Tx` or `Stmt`, those inherit its lack of safety.

+# reflectx
+
+The sqlx package has special reflect needs.  In particular, it needs to:
+
+* be able to map a name to a field
+* understand embedded structs
+* understand mapping names to fields by a particular tag
+* user specified name -> field mapping functions
+
+These behaviors mimic the behaviors by the standard library marshallers and also the
+behavior of standard Go accessors.
+
+The first two are amply taken care of by `Reflect.Value.FieldByName`, and the third is
+addressed by `Reflect.Value.FieldByNameFunc`, but these don't quite understand struct
+tags in the ways that are vital to most marshalers, and they are slow.
+
+This reflectx package extends reflect to achieve these goals.

+
+  An "Application" is any work that makes use of an interface provided

+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is

+
+[![GoDoc](https://godoc.org/github.com/juju/errors?status.svg)](https://godoc.org/github.com/juju/errors)
+
+The juju/errors provides an easy way to annotate errors without losing the
+orginal error context.
+
+The exported `New` and `Errorf` functions are designed to replace the
+`errors.New` and `fmt.Errorf` functions respectively. The same underlying
+error is there, but the package also records the location at which the error
+was created.
+
+A primary use case for this library is to add extra context any time an
+error is returned from a function.
+
+
+	    if err := SomeFunc(); err != nil {
+		    return err
+		}
+
+This instead becomes:
+
+
+	    if err := SomeFunc(); err != nil {
+		    return errors.Trace(err)
+		}
+
+which just records the file and line number of the Trace call, or
+
+
+	    if err := SomeFunc(); err != nil {
+		    return errors.Annotate(err, "more context")
+		}
+
+which also adds an annotation to the error.
+
+When you want to check to see if an error is of a particular type, a helper
+function is normally exported by the package that returned the error, like the
+`os` package does.  The underlying cause of the error is available using the
+`Cause` function.
+
+
+	os.IsNotExist(errors.Cause(err))
+
+The result of the `Error()` call on an annotated error is the annotations joined
+with colons, then the result of the `Error()` method for the underlying error
+that was the cause.
+
+
+	err := errors.Errorf("original")
+	err = errors.Annotatef(err, "context")
+	err = errors.Annotatef(err, "more context")
+	err.Error() -> "more context: context: original"
+
+Obviously recording the file, line and functions is not very useful if you
+cannot get them back out again.
+
+
+	errors.ErrorStack(err)
+
+will return something like:
+
+
+	first error
+	github.com/juju/errors/annotation_test.go:193:
+	github.com/juju/errors/annotation_test.go:194: annotation
+	github.com/juju/errors/annotation_test.go:195:
+	github.com/juju/errors/annotation_test.go:196: more context
+	github.com/juju/errors/annotation_test.go:197:
+
+The first error was generated by an external system, so there was no location
+associated. The second, fourth, and last lines were generated with Trace calls,
+and the other two through Annotate.
+
+Sometimes when responding to an error you want to return a more specific error
+for the situation.
+
+
+	    if err := FindField(field); err != nil {
+		    return errors.Wrap(err, errors.NotFoundf(field))
+		}
+
+This returns an error where the complete error stack is still available, and
+`errors.Cause()` will return the `NotFound` error.
+
+
+
+
+
+
+## func AlreadyExistsf
+``` go
+func AlreadyExistsf(format string, args ...interface{}) error
+```
+AlreadyExistsf returns an error which satisfies IsAlreadyExists().
+
+
+## func Annotate
+``` go
+func Annotate(other error, message string) error
+```
+Annotate is used to add extra context to an existing error. The location of
+the Annotate call is recorded with the annotations. The file, line and
+function are also recorded.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Annotate(err, "failed to frombulate")
+	}
+
+
+## func Annotatef
+``` go
+func Annotatef(other error, format string, args ...interface{}) error
+```
+Annotatef is used to add extra context to an existing error. The location of
+the Annotate call is recorded with the annotations. The file, line and
+function are also recorded.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Annotatef(err, "failed to frombulate the %s", arg)
+	}
+
+
+## func Cause
+``` go
+func Cause(err error) error
+```
+Cause returns the cause of the given error.  This will be either the
+original error, or the result of a Wrap or Mask call.
+
+Cause is the usual way to diagnose errors that may have been wrapped by
+the other errors functions.
+
+
+## func DeferredAnnotatef
+``` go
+func DeferredAnnotatef(err *error, format string, args ...interface{})
+```
+DeferredAnnotatef annotates the given error (when it is not nil) with the given
+format string and arguments (like fmt.Sprintf). If *err is nil, DeferredAnnotatef
+does nothing. This method is used in a defer statement in order to annotate any
+resulting error with the same message.
+
+For example:
+
+
+	defer DeferredAnnotatef(&err, "failed to frombulate the %s", arg)
+
+
+## func Details
+``` go
+func Details(err error) string
+```
+Details returns information about the stack of errors wrapped by err, in
+the format:
+
+
+	[{filename:99: error one} {otherfile:55: cause of error one}]
+
+This is a terse alternative to ErrorStack as it returns a single line.
+
+
+## func ErrorStack
+``` go
+func ErrorStack(err error) string
+```
+ErrorStack returns a string representation of the annotated error. If the
+error passed as the parameter is not an annotated error, the result is
+simply the result of the Error() method on that error.
+
+If the error is an annotated error, a multi-line string is returned where
+each line represents one entry in the annotation stack. The full filename
+from the call stack is used in the output.
+
+
+	first error
+	github.com/juju/errors/annotation_test.go:193:
+	github.com/juju/errors/annotation_test.go:194: annotation
+	github.com/juju/errors/annotation_test.go:195:
+	github.com/juju/errors/annotation_test.go:196: more context
+	github.com/juju/errors/annotation_test.go:197:
+
+
+## func Errorf
+``` go
+func Errorf(format string, args ...interface{}) error
+```
+Errorf creates a new annotated error and records the location that the
+error is created.  This should be a drop in replacement for fmt.Errorf.
+
+For example:
+
+
+	return errors.Errorf("validation failed: %s", message)
+
+
+## func IsAlreadyExists
+``` go
+func IsAlreadyExists(err error) bool
+```
+IsAlreadyExists reports whether the error was created with
+AlreadyExistsf() or NewAlreadyExists().
+
+
+## func IsNotFound
+``` go
+func IsNotFound(err error) bool
+```
+IsNotFound reports whether err was created with NotFoundf() or
+NewNotFound().
+
+
+## func IsNotImplemented
+``` go
+func IsNotImplemented(err error) bool
+```
+IsNotImplemented reports whether err was created with
+NotImplementedf() or NewNotImplemented().
+
+
+## func IsNotSupported
+``` go
+func IsNotSupported(err error) bool
+```
+IsNotSupported reports whether the error was created with
+NotSupportedf() or NewNotSupported().
+
+
+## func IsNotValid
+``` go
+func IsNotValid(err error) bool
+```
+IsNotValid reports whether the error was created with NotValidf() or
+NewNotValid().
+
+
+## func IsUnauthorized
+``` go
+func IsUnauthorized(err error) bool
+```
+IsUnauthorized reports whether err was created with Unauthorizedf() or
+NewUnauthorized().
+
+
+## func Mask
+``` go
+func Mask(other error) error
+```
+Mask hides the underlying error type, and records the location of the masking.
+
+
+## func Maskf
+``` go
+func Maskf(other error, format string, args ...interface{}) error
+```
+Mask masks the given error with the given format string and arguments (like
+fmt.Sprintf), returning a new error that maintains the error stack, but
+hides the underlying error type.  The error string still contains the full
+annotations. If you want to hide the annotations, call Wrap.
+
+
+## func New
+``` go
+func New(message string) error
+```
+New is a drop in replacement for the standard libary errors module that records
+the location that the error is created.
+
+For example:
+
+
+	return errors.New("validation failed")
+
+
+## func NewAlreadyExists
+``` go
+func NewAlreadyExists(err error, msg string) error
+```
+NewAlreadyExists returns an error which wraps err and satisfies
+IsAlreadyExists().
+
+
+## func NewNotFound
+``` go
+func NewNotFound(err error, msg string) error
+```
+NewNotFound returns an error which wraps err that satisfies
+IsNotFound().
+
+
+## func NewNotImplemented
+``` go
+func NewNotImplemented(err error, msg string) error
+```
+NewNotImplemented returns an error which wraps err and satisfies
+IsNotImplemented().
+
+
+## func NewNotSupported
+``` go
+func NewNotSupported(err error, msg string) error
+```
+NewNotSupported returns an error which wraps err and satisfies
+IsNotSupported().
+
+
+## func NewNotValid
+``` go
+func NewNotValid(err error, msg string) error
+```
+NewNotValid returns an error which wraps err and satisfies IsNotValid().
+
+
+## func NewUnauthorized
+``` go
+func NewUnauthorized(err error, msg string) error
+```
+NewUnauthorized returns an error which wraps err and satisfies
+IsUnauthorized().
+
+
+## func NotFoundf
+``` go
+func NotFoundf(format string, args ...interface{}) error
+```
+NotFoundf returns an error which satisfies IsNotFound().
+
+
+## func NotImplementedf
+``` go
+func NotImplementedf(format string, args ...interface{}) error
+```
+NotImplementedf returns an error which satisfies IsNotImplemented().
+
+
+## func NotSupportedf
+``` go
+func NotSupportedf(format string, args ...interface{}) error
+```
+NotSupportedf returns an error which satisfies IsNotSupported().
+
+
+## func NotValidf
+``` go
+func NotValidf(format string, args ...interface{}) error
+```
+NotValidf returns an error which satisfies IsNotValid().
+
+
+## func Trace
+``` go
+func Trace(other error) error
+```
+Trace adds the location of the Trace call to the stack.  The Cause of the
+resulting error is the same as the error parameter.  If the other error is
+nil, the result will be nil.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Trace(err)
+	}
+
+
+## func Unauthorizedf
+``` go
+func Unauthorizedf(format string, args ...interface{}) error
+```
+Unauthorizedf returns an error which satisfies IsUnauthorized().
+
+
+## func Wrap
+``` go
+func Wrap(other, newDescriptive error) error
+```
+Wrap changes the Cause of the error. The location of the Wrap call is also
+stored in the error stack.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    newErr := &packageError{"more context", private_value}
+	    return errors.Wrap(err, newErr)
+	}
+
+
+## func Wrapf
+``` go
+func Wrapf(other, newDescriptive error, format string, args ...interface{}) error
+```
+Wrapf changes the Cause of the error, and adds an annotation. The location
+of the Wrap call is also stored in the error stack.
+
+For example:
+
+
+	if err := SomeFunc(); err != nil {
+	    return errors.Wrapf(err, simpleErrorType, "invalid value %q", value)
+	}
+
+
+
+## type Err
+``` go
+type Err struct {
+    // contains filtered or unexported fields
+}
+```
+Err holds a description of an error along with information about
+where the error was created.
+
+It may be embedded in custom error types to add extra information that
+this errors package can understand.
+
+
+
+
+
+
+
+
+
+### func NewErr
+``` go
+func NewErr(format string, args ...interface{}) Err
+```
+NewErr is used to return an Err for the purpose of embedding in other
+structures.  The location is not specified, and needs to be set with a call
+to SetLocation.
+
+For example:
+
+
+	type FooError struct {
+	    errors.Err
+	    code int
+	}
+	
+	func NewFooError(code int) error {
+	    err := &FooError{errors.NewErr("foo"), code}
+	    err.SetLocation(1)
+	    return err
+	}
+
+
+
+
+### func (\*Err) Cause
+``` go
+func (e *Err) Cause() error
+```
+The Cause of an error is the most recent error in the error stack that
+meets one of these criteria: the original error that was raised; the new
+error that was passed into the Wrap function; the most recently masked
+error; or nil if the error itself is considered the Cause.  Normally this
+method is not invoked directly, but instead through the Cause stand alone
+function.
+
+
+
+### func (\*Err) Error
+``` go
+func (e *Err) Error() string
+```
+Error implements error.Error.
+
+
+
+### func (\*Err) Location
+``` go
+func (e *Err) Location() (filename string, line int)
+```
+Location is the file and line of where the error was most recently
+created or annotated.
+
+
+
+### func (\*Err) Message
+``` go
+func (e *Err) Message() string
+```
+Message returns the message stored with the most recent location. This is
+the empty string if the most recent call was Trace, or the message stored
+with Annotate or Mask.
+
+
+
+### func (\*Err) SetLocation
+``` go
+func (e *Err) SetLocation(callDepth int)
+```
+SetLocation records the source location of the error at callDepth stack
+frames above the call.
+
+
+
+### func (\*Err) StackTrace
+``` go
+func (e *Err) StackTrace() []string
+```
+StackTrace returns one string for each location recorded in the stack of
+errors. The first value is the originating error, with a line for each
+other annotation or tracing of the error.
+
+
+
+### func (\*Err) Underlying
+``` go
+func (e *Err) Underlying() error
+```
+Underlying returns the previous error in the error stack, if any. A client
+should not ever really call this method.  It is used to build the error
+stack and should not be introspected by client calls.  Or more
+specifically, clients should not depend on anything but the `Cause` of an
+error.

+# UUID package for Go language
+
+[![Build Status](https://travis-ci.org/satori/go.uuid.png?branch=master)](https://travis-ci.org/satori/go.uuid)
+[![GoDoc](http://godoc.org/github.com/satori/go.uuid?status.png)](http://godoc.org/github.com/satori/go.uuid)
+
+This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs.
+
+With 100% test coverage and benchmarks out of box.
+
+Supported versions:
+* Version 1, based on timestamp and MAC address (RFC 4122)
+* Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
+* Version 3, based on MD5 hashing (RFC 4122)
+* Version 4, based on random numbers (RFC 4122)
+* Version 5, based on SHA-1 hashing (RFC 4122)
+
+## Installation
+
+Use the `go` command:
+
+	$ go get github.com/satori/go.uuid
+
+## Requirements
+
+UUID package requires any stable version of Go Programming Language.
+
+It is tested against following versions of Go: 1.0, 1.1, 1.2
+
+## Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/satori/go.uuid"
+)
+
+func main() {
+	// Creating UUID Version 4
+	u1 := uuid.NewV4()
+	fmt.Printf("UUIDv4: %s\n", u1)
+
+	// Parsing UUID from string input
+	u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
+	if err != nil {
+		fmt.Printf("Something gone wrong: %s", err)
+	}
+	fmt.Printf("Successfully parsed: %s", u2)
+}
+```
+
