deb2appimage uses deb packages from Debian's and/or Ubuntu's repos to build AppImages based on simple JSON configuration. The debs are downloaded using curl and extracted using ar x so that AppImages can be built from any distribution. The JSON configuration files are setup in a way that they should be easy to understand, yet flexible enough to work with AppImages that require extra tweaking before building. ~/.cache/deb2appimage is used as a temporary directory for building AppImages, and is deleted after run.
