These are PKGBUILDs for the Arch User Repository (AUR). The AUR hosts user supplied source package definitons for Arch Linux.
Starting with AUR 4 every package is in a separate git repository. These are only included as submodules here. The packages I maintain are listed here: Packages by JonnyJD
There are no GitHub clones of the submodules. Please report issues and link patches (git format-patch) in the package comments at the AUR.
In _bin you can find scripts to manage AUR 4 packages as submodules.
