-GtkBuilder File Utility
------------------------
-
-SYNOPSIS
---------
-|   **gtk4-builder-tool** <COMMAND> [OPTIONS...] <FILE>
-|
-|   **gtk4-builder-tool** validate <FILE>
-|   **gtk4-builder-tool** enumerate <FILE>
-|   **gtk4-builder-tool** simplify [OPTIONS...] <FILE>
-|   **gtk4-builder-tool** preview [OPTIONS...] <FILE>
-
-DESCRIPTION
------------
-
-``gtk4-builder-tool`` can perform various operations on GtkBuilder UI definition
-files.
-
-COMMANDS
---------
-
-Validation
-^^^^^^^^^^
-
-The ``validate`` command validates the given UI definition file and reports
-errors to ``stderr``.
-
-Enumeration
-^^^^^^^^^^^
-
-The ``enumerate`` command lists all the named objects that are present in the UI
-definition file.
-
-Preview
-^^^^^^^
-
-The ``preview`` command displays the UI dfinition file.
-
-This command accepts options to specify the ID of the toplevel object and a CSS
-file to use.
-
-``--id=ID``
-
-  The ID of the object to preview. If not specified, gtk4-builder-tool will
-  choose a suitable object on its own.
-
-``--css=FILE``
-
-  Load style information from the given CSS file.
-
-Simplification
-^^^^^^^^^^^^^^
-
-The ``simplify`` command simplifies the UI definition file by removing
-properties that are set to their default values and writes the resulting XML to
-the standard output, or back to the input file.
-
-When the ``--3to4`` option is specified, the ``simplify`` command interprets the
-input as a GTK 3 UI definuition file and attempts to convert it to GTK 4
-equivalents. It performs various conversions, such as renaming properties,
-translating child properties to layout properties, rewriting the setup for
-GtkNotebook, GtkStack, GtkAssistant  or changing toolbars into boxes.
-
-You should always test the modified UI definition files produced by
-gtk4-builder-tool before using them in production.
-
-Note in particular that the conversion done with ``--3to4`` is meant as a
-starting point for a port from GTK 3 to GTK 4. It is expected that you will have
-to do manual fixups  after the initial conversion.
-
-``--replace``
-
-  Write the content back to the UI definition file instead of using the standard
-  output.
-
-``--3to4``
-
-  Transform a GTK 3 UI definition file to the equivalent GTK 4 definitions.

-SYNOPSIS
---------
-

-
-DESCRIPTION
------------
-
-``gtk4-encode-symbolic-svg`` converts symbolic SVG icons into specially prepared
-PNG files. GTK can load and recolor these PNGs, just like original SVGs, but
-loading them is much faster.
-
-``PATH`` is the name of a symbolic SVG file, ``WIDTH`` x ``HEIGHT`` are the
-desired dimensions for the generated PNG file.
-
-To distinguish them from ordinary PNGs, the generated files have the extension
-``.symbolic.png``.
-
-OPTIONS
--------
-
-``-o, --output DIRECTORY``
-
-  Write png files to ``DIRECTORY`` instead of the current working directory.
-
-``--debug``
-
-  Generate PNG files of the various channels during the conversion. If these
-  files are not monochrome green, they are often helpful in pinpointing the
-  problematic parts of the source SVG.

-Icon theme caching utility
---------------------------
-
-SYNOPSIS
---------
-
-|   **gtk4-update-icon-cache** [OPTIONS...] <PATH>
-
-DESCRIPTION
------------
-
-``gtk4-update-icon-cache`` creates ``mmap(2)``-able cache files for icon themes.
-
-It expects to be given the ``PATH`` to an icon theme directory containing an
-``index.theme``, e.g. ``/usr/share/icons/hicolor``, and writes a
-``icon-theme.cache`` containing cached information about the icons in the
-directory tree below the given directory.
-
-GTK can use the cache files created by ``gtk4-update-icon-cache`` to avoid a lot
-of system call and disk seek overhead when the application starts. Since the
-format of the cache files allows them to be shared across multiple processes,
-for instance using the POSIX ``mmap(2)`` system call, the overall memory
-consumption is reduced as well.
-
-OPTIONS
--------
-
-``-f, --force``
-
-  Overwrite an existing cache file even if it appears to be up-to-date.
-
-``-t, --ignore-theme-index``
-
-  Don't check for the existence of ``index.theme`` in the icon theme directory.
-  Without this option, ``gtk4-update-icon-cache`` refuses to create an icon
-  cache in a directory which does not appear to be the toplevel directory of an
-  icon theme.
-
-``-i, --index-only``
-
-  Don't include image data in the cache.
-
-``--include-image-data``
-
-  Include image data in the cache.
-
-``-c, --source <NAME>``
-
-  Output a C header file declaring a constant ``NAME`` with the contents of the
-  icon cache.
-
-``-q, --quiet``
-
-  Turn off verbose output.
-
-``-v, --validate``
-
-  Validate existing icon cache.
