+# [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.
