* Numerous mini valgrind fixes.
* Addition of hacky architecture check in the _splitname function * Removal of libfetch from the archlinux proper - it has been renamed to libdownload and can be found at http://phraktured.net/libdownload * Merge of _some_ of the Frugalware makepkg change - this may still be incomplete * Removal of libftp from cvs proper * PKGBUILD manpage now says 'PKGBUILD' instead of FrugalBuild (he he)
