Blubee Supports Arch

Blubee can now be built for Arch, blubee builds something similar to an AUR package that can be packaged and installed with makepkg(and optionally pacman -U). These files can be found in dist/blubee_<version>_all after one runs the build script.

The default backup directory for deleted and changed files during restore has moved from /var/local to /var/lib.
