From: "Jason St. John"
Several grammatical errors and minor formatting consistency issues have been resolved in
PKGBUILD(5).
The pkgver() function is now fully documented in PKGBUILD(5), including
several usage examples taken from ArchWiki. The "Using VCS Sources"
section now states that CVS and Darcs are not natively supported in
makepkg.
The example PKGBUILD for 'patch' was rather basic and lacked the
prepare() and check() functions. The PKGBUILD was also rather dated
compared to the current, official PKGBUILD. The new example PKGBUILD is
a lot more complete and displays more features of makepkg.
