..
Normally, there are no heading levels assigned to certain characters as the structure is
determined from the succession of headings. However, this convention is used in Python’s
Style Guide for documenting which you may follow:
# with overline, for parts
* for chapters
= for sections
- for subsections
^ for subsubsections
" for paragraphs

Scripting
#########################
This is a list of how certain tasks may be accomplished when you use
restic via scripts.
Check if a repository is already initialized
********************************************
You may find a need to check if a repository is already initialized,
perhaps to prevent your script from initializing a repository multiple

times. The command ``cat config`` may be used for this purpose:

If a repository does not exist, restic will return a non-zero exit code
and print an error message. Note that restic will also return a non-zero
exit code if a different error is encountered (e.g.: incorrect password

to ``cat config``) and it may print a different error message. If there
are no errors, restic will return a zero exit code and print the repository
metadata.
add json documentation

Restic and json
***************
Restic can output json data if requested with the ``--json`` flag.
The structure of that data varies depending on the circumstance. The
json output of Most restic commands are documented here.
.. note::
Not all commands support json output. If a command does not support json output,
at the time of writing, it is not supported yet. (feel free to submit a pull request!)
