+# gitpkgv.bbclass provides a GITPKGV variable which is a sortable version
+# with the format NN+GITHASH, to be used in PKGV, where
+#
+# NN equals the total number of revs up to SRCREV
+# GITHASH is SRCREV's (full) hash
+#
+# gitpkgv.bbclass assumes the git repository has been cloned, and contains
+# SRCREV. So ${GITPKGV} should never be used in PV, only in PKGV.
+# It can handle SRCREV = ${AUTOREV}, as well as SRCREV = "<some fixed git hash>"
+#
+# use example:
+#
+# inherit gitpkgv
+#
+# PV = "1.0+git${SRCPV}"
+# PKGV = "1.0+git${GITPKGV}"
