# The entire source is (Apache-2.0 OR GPL-3.0-or-later) except the following files that are

#
# (Apache-2.0 OR GPL-3.0-or-later) AND BSD-2-Clause:

# MIT:

# CC0-1.0:

#   - gidocgen/templates/basic/*.png

#   - examples/*.toml (-doc subpackage)
#
# Note that CC0-1.0 is allowed in Fedora for content only; all of the above
# files may reasonably be called content.
#
# Additionally, CC0-1.0 appears in certain sample configuration snippets within
# the following files, which are otherwise (Apache-2.0 OR GPL-3.0-or-later):
#   - docs/project-configuration.rst
#   - docs/tutorial.rst
# On one hand, these are copied from real projects; on the other hand, they are
# very trivial. It’s not obvious whether they should be considered “real”
# CC0-1.0 content or not.
#
# The identifier LGPL-2.1-or-later also appears in a sample configuration
# template in docs/tutorial.rst, but the configuration in question is filled
# with placeholder values and is not copied from a real project, so it’s
# reasonable to consider LGPL-2.1-or-later a placeholder rather than a real
# license as well.

%description
GI-DocGen is a document generator for GObject-based libraries. GObject is the
base type system of the GNOME project. GI-Docgen reuses the introspection data
generated by GObject-based libraries to generate the API reference of these
libraries, as well as other ancillary documentation.

GI-DocGen is not a general purpose documentation tool for C libraries.

While GI-DocGen can be used to generate API references for most GObject/C
libraries that expose introspection data, its main goal is to generate the
reference for GTK and its immediate dependencies. Any and all attempts at
making this tool more generic, or to cover more use cases, will be weighted
heavily against its primary goal.

GI-DocGen is still in development. The recommended use of GI-DocGen is to add
it as a sub-project to your Meson build system, and vendor it when releasing
dist archives.

You should not depend on a system-wide installation until GI-DocGen is declared
stable.

%description fonts
Because web fonts from upstream are not bundled in the gi-docgen package,
documentation packages generated with gi-docgen must depend on this metapackage
to ensure the proper system fonts are present.
