|
|
# The purpose of this script is to provide lightweight desktop integration
|
|
# into the host system without special help from the host system.
|
|
# If you want to use it, then place this in usr/bin/$APPNAME.wrapper
|
|
# and set it as the Exec= line of the .desktop file in the AppImage.
|
|
#
|
|
# For example, to install the appropriate icons for Scribus,
|
|
# put them into the AppDir at the following locations:
|
|
#
|
|
# ./usr/share/icons/default/128x128/apps/scribus.png
|
|
# ./usr/share/icons/default/128x128/mimetypes/application-vnd.scribus.png
|
|
#
|
|
# Note that the filename application-vnd.scribus.png is derived from
|
|
# and must be match MimeType=application/vnd.scribus; in scribus.desktop
|
|
# (with "/" characters replaced by "-").
|
|
#
|
|
# Then, change Exec=scribus to Exec=scribus.wrapper and place the script
|
|
# below in usr/bin/scribus.wrapper and make it executable.
|
|
# When you run AppRun, then AppRun runs the wrapper script below
|
|
# which in turn will run the main application.
|
|
#
|
|
# TODO:
|
|
# Handle multiple versions of the same AppImage?
|
|
# Handle removed AppImages? Currently we are just setting TryExec=
|
|
# See http://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html#DELETE
|
|
# Possibly move this to the C runtime that is part of every AppImage?
|
|
|

# Exit on errors
