# 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
