Sorry for asking newbie questions.
As far as I know
appimagetool is the tool creating AppImages
linuxdeploy is designed to be an AppDir maintenance tool.
However, it seems I can just use linuxdeploy with its plugin to create a AppImage file.
./linuxdeploy*.AppImage --appdir AppDir --output appimage
appimagetool seems has nothing to do.
when should I use appimagetool?
Besides, I was wondering why linuxdeploy skips those runtime libraries (such as /usr/lib/x86_64-linux-gnu/libstdc++.so.6)
when deploying dependencies
