boxxy is a tool for boxing up misbehaving Linux applications and forcing them to put their files and directories in the right place, without symlinks! - boxxy / HN

Features

• box any program and force it to put its files/directories where you want it to
• context-dependent boxing, ie different rules apply in different directories depending on your configuration

AppImage have to be handled like a docker image: just use the --appimage-extract-and-runparameter to the AppImage in your call, eg:

$ ./boxxy -l debug ~/app/digiKam-8.1.0-x86-64.appimage --appimage-extract-and-run
