# !!! DEPRECATED !!!
#
# [DEPLOY_QT=1] deploy-linux.sh <executable>
#   (Simplified) bash re-implementation of [linuxdeploy](https://github.com/linuxdeploy).
#   Reads [executable] and copies required libraries to [AppDir]/usr/lib
#   Copies the desktop and svg icon to [AppDir]
#   Respects the AppImage excludelist
#
# Unlike linuxdeploy, this does not:
# - Copy any icon other than svg (too lazy to add that without a test case)
# - Do any verification on the desktop file
# - Run any linuxdeploy plugins
# - *Probably other things I didn't know linuxdeploy can do*
#
# It notably also does not copy unneeded libraries, unlike linuxdeploy. On a desktop system, this
# can help reduce the end AppImage's size, although in a production system this script proved
# unhelpful.
