GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the 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 Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

Basic Installation
|
||||
==================
|
||||
|
||||
These are generic installation instructions.
|
||||
|
||||
The `configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a `Makefile' in each directory of the package.
|
||||
It may also create one or more `.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script `config.status' that
|
||||
you can run in the future to recreate the current configuration, a file
|
||||
`config.cache' that saves the results of its tests to speed up
|
||||
reconfiguring, and a file `config.log' containing compiler output
|
||||
(useful mainly for debugging `configure').
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how `configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the `README' so they can
|
||||
be considered for the next release. If at some point `config.cache'
|
||||
contains results you don't want to keep, you may remove or edit it.
|
||||
|
||||
The file `configure.in' is used to create `configure' by a program
|
||||
called `autoconf'. You only need `configure.in' if you want to change
|
||||
it or regenerate `configure' using a newer version of `autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. `cd' to the directory containing the package's source code and type
|
||||
`./configure' to configure the package for your system. If you're
|
||||
using `csh' on an old version of System V, you might need to type
|
||||
`sh ./configure' instead to prevent `csh' from trying to execute
|
||||
`configure' itself.
|
||||
|
||||
Running `configure' takes awhile. While running, it prints some
|
||||
messages telling which features it is checking for.
|
||||
|
||||
2. Type `make' to compile the package.
|
||||
|
||||
3. Optionally, type `make check' to run any self-tests that come with
|
||||
the package.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation.
|
||||
|
||||
5. You can remove the program binaries and object files from the
|
||||
source code directory by typing `make clean'. To also remove the
|
||||
files that `configure' created (so you can compile the package for
|
||||
a different kind of computer), type `make distclean'. There is
|
||||
also a `make maintainer-clean' target, but that is intended mainly
|
||||
for the package's developers. If you use it, you may have to get
|
||||
all sorts of other programs in order to regenerate files that came
|
||||
with the distribution.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that
|
||||
the `configure' script does not know about. You can give `configure'
|
||||
initial values for variables by setting them in the environment. Using
|
||||
a Bourne-compatible shell, you can do that on the command line like
|
||||
this:
|
||||
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
|
||||
|
||||
Or on systems that have the `env' program, you can do it like this:
|
||||
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you must use a version of `make' that
|
||||
supports the `VPATH' variable, such as GNU `make'. `cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the `configure' script. `configure' automatically checks for the
|
||||
source code in the directory that `configure' is in and in `..'.
|
||||
|
||||
If you have to use a `make' that does not supports the `VPATH'
|
||||
variable, you have to compile the package for one architecture at a time
|
||||
in the source code directory. After you have installed the package for
|
||||
one architecture, use `make distclean' before reconfiguring for another
|
||||
architecture.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' will install the package's files in
|
||||
`/usr/local/bin', `/usr/local/man', etc. You can specify an
|
||||
installation prefix other than `/usr/local' by giving `configure' the
|
||||
option `--prefix=PATH'.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
give `configure' the option `--exec-prefix=PATH', the package will use
|
||||
PATH as the prefix for installing programs and libraries.
|
||||
Documentation and other data files will still use the regular prefix.
|
||||
|
||||
In addition, if you use an unusual directory layout you can give
|
||||
options like `--bindir=PATH' to specify different values for particular
|
||||
kinds of files. Run `configure --help' for a list of the directories
|
||||
you can set and what kinds of files go in them.
|
||||
|
||||
If the package supports it, you can cause programs to be installed
|
||||
with an extra prefix or suffix on their names by giving `configure' the
|
||||
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to
|
||||
`configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
|
||||
is something like `gnu-as' or `x' (for the X Window System). The
|
||||
`README' should mention any `--enable-' and `--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, `configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the `configure' options `--x-includes=DIR' and
|
||||
`--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' can not figure out
|
||||
automatically, but needs to determine by the type of host the package
|
||||
will run on. Usually `configure' can figure that out, but if it prints
|
||||
a message saying it can not guess the host type, give it the
|
||||
`--host=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name with three fields:
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
See the file `config.sub' for the possible values of each field. If
|
||||
`config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the host type.
|
||||
|
||||
If you are building compiler tools for cross-compiling, you can also
|
||||
use the `--target=TYPE' option to select the type of system they will
|
||||
produce code for and the `--build=TYPE' option to select the type of
|
||||
system on which you are compiling the package.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for `configure' scripts to share,
|
||||
you can create a site shell script called `config.site' that gives
|
||||
default values for variables like `CC', `cache_file', and `prefix'.
|
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then
|
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
`CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all `configure' scripts look for a site script.
|
||||
|
||||
Operation Controls
|
||||
==================
|
||||
|
||||
`configure' recognizes the following options to control how it
|
||||
operates.
|
||||
|
||||
`--cache-file=FILE'
|
||||
Use and save the results of the tests in FILE instead of
|
||||
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
|
||||
debugging `configure'.
|
||||
|
||||
`--help'
|
||||
Print a summary of the options to `configure', and exit.
|
||||
|
||||
`--quiet'
|
||||
`--silent'
|
||||
`-q'
|
||||
Do not print messages saying which checks are being made. To
|
||||
suppress all normal output, redirect it to `/dev/null' (any error
|
||||
messages will still be shown).
|
||||
|
||||
`--srcdir=DIR'
|
||||
Look for the package's source code in directory DIR. Usually
|
||||
`configure' can determine that directory automatically.
|
||||
|
||||
`--version'
|
||||
Print the version of Autoconf used to generate the `configure'
|
||||
script, and exit.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options.

lsyncd - Live Syncing (Mirror) Daemon
|
||||
|
||||
DESCRIPTION:
|
||||
|
||||
Lsyncd uses rsync to synchronize local directories with a remote machine
|
||||
running rsyncd. Lsyncd watches multiple directories trees through inotify.
|
||||
The first step after adding the watches is to, rsync all directories with
|
||||
the remote host, and then sync single file buy collecting the inotify events.
|
||||
|
||||
So lsyncd is a light-weight live mirror solution that should be easy to
|
||||
install and use while blending well with your system.
|
||||
|
||||
See lsyncd --help for detailed command line options.
|
||||
|
||||
WHEN TO USE:
|
||||
|
||||
Lsyncd is designed to synchronize a local directory tree with low profile of
|
||||
expected changes to a remote mirror. On the receivers side rsyncd can be
|
||||
configured to also change the uid/gid of the file. Lsyncd is especially
|
||||
useful to sync data from a secure area to a not-so-secure area (e.g. as a
|
||||
one way connection to allow employees to publish their files to a public
|
||||
accessible web server).
|
||||
|
||||
WHEN NOT TO USE:
|
||||
|
||||
* File with active file handles (e.g. database files)
|
||||
* Directories where many changes occur (like mail or news servers)
|
||||
|
||||
In these cases e.g. DRBD (see http://www.linux-ha.org/DRBD) might be better
|
||||
for you.
|
||||
|
||||
COMPARISONS:
|
||||
|
||||
Lsyncd vs. DRBD:
|
||||
|
||||
DRBD operates on block device level. This makes it useful for
|
||||
synchronizing systems that are under heavy load. Lsyncd on the other hand
|
||||
|
||||
* does not require you to change block devices and/or mount points.
|
||||
* allows you to change uid/gid of the transferred files.
|
||||
* separates the receiver through the one-way nature of rsync.
|
||||
|
||||
However when using lsyncd a file change can possibly result in a full file
|
||||
transfer (at least for binary files) and is therefore unsuitable for
|
||||
databases. Also a directory rename will result in transferring the whole
|
||||
directory.
|
||||
|
||||
Lsyncd vs. incron:
|
||||
|
||||
Incron does not (yet) support recursive directory watching making it
|
||||
unsuitable for described needs (http://inotify.aiken.cz/?section=incron&page=about&lang=en).
|
||||
In fact a different approach would have been to extent incron. However, we
|
||||
decided to stick to the NIH principle (Not Invented Here) :-), because extending
|
||||
the C++ solution seemed to tedious.
|
||||
|
||||
Lsyncd vs. FUSE:
|
||||
|
||||
This is another interesting idea is to write a daemon that provides a
|
||||
shadow file system through fuse. When accessing a file the data is synced
|
||||
to local file as well as the remote file. Whit this approach inotify could
|
||||
be replaced. BindFS (see http://www.cs.helsinki.fi/u/partel/bindfs/)
|
||||
does this for local mirroring. We discarded this idea because it would
|
||||
affect performance of normal operations in a negative way.
|
||||
|
||||
Lsyncd vs. cron:
|
||||
|
||||
If you find a solution using cron to call rsync over the whole directory
|
||||
tree periodically after every 'X' hours/minutes/seconds more satisfying
|
||||
than lsyncd, please go for it *sulking*. We don't like it!
|
||||
|
||||
LSYNCD USAGE EXAMPLES:
|
||||
|
||||
/usr/sbin/lsyncd /var/www/ remotehost::wwwshare/
|
||||
|
||||
This watches and rsycn's the local directory /var/www/ with all
|
||||
subdirectories and transfers them to 'remotehost' using the rsync-share
|
||||
'wwwshare'.
|
||||
|
||||
/usr/sbin/lsyncd --nodaemon --exclude-from /etc/lsycnd/exclude \
|
||||
/var/www/ remotehost::wwwshare/
|
||||
|
||||
This will also rsync/watch '/var/www', but it excludes files and directories
|
||||
from '/etc/lsycnd/exclude'. Additionally this example lsyncd will not fork,
|
||||
and log to stdout/stderr instead.
|
||||
|
||||
/usr/sbin/lsyncd %userwww remotehost::wwwshare/foobar/
|
||||
|
||||
This special target will scan through all directories in /home and syncs all
|
||||
www subdirectories of the users to wwwshare in the subdirectory foobar.
|
||||
The user peter having his local data in /home/peter/www/ will have it
|
||||
rsynced to ::wwwshare/foobar/peter/.
|
||||
|
||||
LIMITATIONS:
|
||||
Be aware that the kernel limits the number of watches. You can see the limit
|
||||
in
|
||||
/proc/sys/fs/inotify/max_user_watches
|
||||
|
||||
which is usually set to 8192. This means lsyncd cannot watch more than 8192
|
||||
directories unless you change the kernel setting. Lsyncd itself has no
|
||||
limits.
|
||||
|
||||
Because Axel is lazy the maximum possible size a filename is 8192. If you
|
||||
need more, change MAX_PATH in lsyncd.c. Or send me patches that introduce
|
||||
dynamic memory usage.
|
||||
|
||||
SOURCE DOCUMENTATION:
|
||||
|
||||
The only file of interest is 'lsyncd.c' which includes comments.
|
||||
Everything else in the tarball is packaging bushwa.
|
||||
|
||||
DISCLAIMER:
|
||||
|
||||
Besides the usual disclaimer in the license, we want to specifically EMPHASIZE
|
||||
that NEITHER the authors NOR any organization the authors are associated with
|
||||
can and will hold responsible for data-loss caused by possible malfunctions
|
||||
of lsyncd. Especially if you run it with root privileges ;-) (we ourselves
|
||||
run lsyncd as www-data).

* React on signal HUP resync and rewatch everything.
|
||||
* Allow several source->target specifications.
|
||||
* Allow more complicated source masks like /home/%1/www/ -> target::%1/
|
||||
* Workaround the default 8192 watches kernel limit by opening another inotify
|
||||
instance when needed.
|
||||
* React on inotify OVERFLOW messages in resyncing everything, something might
|
||||
have been missed.
|
||||
* Allow more complicated exclusion masks.
|
||||
* Do not call rsync at all if a file was edited that falls under the exclusion
|
||||
mask (currently it is called, and rsync drops it.
|
||||
* When several things happen at once, wait if calls to rsync can be optimized
|
||||
* Allow users to specificy more rsync call options.
|
||||
* Make a manpage.
|
||||
* improve config.h.in generation
