Tests:

Test appdata no (appstream-util not found)
Test desktop file yes

Bug report URL: https://gitlab.gnome.org/GNOME/gimp/issues/new

NOTE: if you plan on packaging GIMP for distribution, it is recommended
to override the bug report URL with option:
--with-bug-report-url=https://example.com/
so that you can filter packaging bugs from core bugs before
reporting upstream.

Error: GIMP configuration failed.

- PyCairo 1.0.2 or newer
*** Please install it, or skip building the python scripting extension by
*** passing --disable-python to configure (but then you will not be able
*** to use scripts for GIMP that are written in Python).

See the file 'INSTALL' for more help.
