# Use this script to run different sanity checks for the APP_DIR used for AppImage
#
# It will check the
# - glibc, libdtdc++ versions required
# - unreseolved dynamic libraries
# - issues with rpaths and interpreter
#
# You can run this script on build machine after APP_DIR is prepared,
# but also on the client machine, which will run the AppImage (useful for ldd check).
# You need to extract AppImage with `--appimage-extract`
