"""Sphinx extension creating a link to an archive.
This Sphinx extension adds the possibility to create a zip archive and
include it in the generated HTML documentation.
This extension provides an *archive* directive.
Usage:
.. archive:: <relative_path/to/directory/to/compress>
:filename: <name_of_the_archive_file, default: last_folder_of_directory.zip>
:filter: <Space-separated list of included file patterns, default *.*>
:basedir: <Name of the base directory in the archive, default: filename>
Examples:
To create a example.zip archive of the ../../example/ folder:
.. archive:: ../../examples/
To get more control on the name of the archive and its content:
.. archive:: ../../examples/
:filename: myproject_examples.zip
:filter: *.py *.png
:basedir: myproject_examples
WARNING: The content of this directory is not checked for outdated documents.
