# ${PV} comes in the form of x.y.z.YYYYMMDD where x.y.z is the original (unpatched) version
# and YYYYMMDD is the patch's datestamp. The patch lives on a gentoo mirror and is called
# ${PN}-x.y.z-YYYYMMDD.diff. We figure out automagically the two parts of the current $PV.

# I'm not that good at regexps etc., so I emulate std coding practices
