pkgconfig is a part of base-devel

According to the arch linux wiki it can thus be assumed that it is

Accidentally striped the original maintainer / contributer comments
Custom nmap PKGBUILD

Without ndiff, ncat, zenmap and lua
Custom redshift PKGBUILD

Without gconf, geoclue and gui
custom mpd build
mpd: removed prepare function
added pkgdiff helper script
mpd: disable opus support since ffmpeg supports it
updated pkgdiff script - now works with uzbl too
more minimal custom mpv build
add mpv to modified group
Updated directory tree

'abs' contains modified packages from abs. 'aur' contains modified
packages from aur.
simplified pkgdiff.sh
License pkgdiff.sh under GPLv3
removed prepare function from msmtp build
build mpd with even less features

I should really start building the packages in a chroot...
