# This Snapcraft file and the resulting Snap is NOT OFFICIALLY SUPPORTED.
# If you can, please use a provided native build for your distribution.
# Patches to improve this file are very welcome though, and so is testing the Snap!
#
# This snap is strict, but it has an important limitation:
# - it needs read/write access to wherever the user puts the workspace
#   definition (could be anywhere, but most commonly it's in /srv, in /home or
#   in /var), access to a local archive mount (can be in /mnt), and that should
#   be it (unless optipng and ffprobe have extra requirements).
#
# Until that is overcome, this snap should be installed using `--devmode` to
# effectively disable the confinement.
#
# This Snap is autobuilt, you can check its status at https://build.snapcraft.io/user/ximion/appstream-generator

  # This is a work-around for the broken Gdk Pixbuf in the Gnome SDK

  #   https://github.com/ubuntu/gnome-sdk/issues/357

  #   formats we require to run normally (png/svg/jpeg). This may be a problem
