Arch Linux

Description:

Now that we have these in makepkg:

*tar.gz) ${COMPRESSGZ[@]:-gzip -c -f -n} ;;
*tar.bz2) ${COMPRESSBZ2[@]:-bzip2 -c -f} ;;
*tar.xz) ${COMPRESSXZ[@]:-xz -c -z -} ;;
*tar.lrz) ${COMPRESSLRZ[@]:-lrzip -q} ;;
*tar.lzo) ${COMPRESSLZO[@]:-lzop -q} ;;
*tar.Z) ${COMPRESSZ[@]:-compress -c -f} ;;

..the ones outside of [core] (or maybe even them?) should be included in the optional dependencies (which currently lists only fakeroot).

The names of these things are:

.tar.gz = gzip [core]
.tar.gz2 = bzip2 [core]
.tar.xz = xz [core]
.tar.lrz = lrzip [community]
.tar.lzo = lzop [extra]
.tar.Z = compress (?) (I dunno, I couldn't find it anywhere - not even with `pkgfile`)

Additional info:
* pacman 4.1.0-2
