+# gitpkgv.bbclass provides a GITPKGV and GITPKGVTAG variables to be
+# used in PKGV, as described bellow:
+#
+# - GITPKGV 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
+#
+# - GITPKGVTAG which is the output of 'git describe' allowing for
+#   automatic versioning
+#
+# gitpkgv.bbclass assumes the git repository has been cloned, and
+# contains SRCREV. So ${GITPKGV} and ${GITPKGVTAG} should never be
+# used in PV, only in PKGV.  It can handle SRCREV = ${AUTOREV}, as
+# well as SRCREV = "<some fixed git hash>".
+#
+# WARNING: if upstream repository is always using consistent and
+# sortable tag name scheme you can get sortable version including tag
+# name with ${GITPKGVTAG}, but be aware that ie tag sequence "v1.0,
+# v1.2, xtest, v2.0" will force you to increment PE to get upgradeable
+# path to v2.0 revisions
+#
+# use example:
+#
+# inherit gitpkgv
+#
+# PV = "1.0+gitr${SRCPV}"      # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b
+# PKGV = "1.0+gitr${GITPKGV}"  # expands also to something like 1.0+gitr31337+4c1c21d7d
+#
+# or
+#
+# inherit gitpkgv
+#
+# PV = "1.0+gitr${SRCPV}" # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b
+# PKGV = "${GITPKGVTAG}"  # expands to something like 1.0-31337+g4c1c21d
+#                           if there is tag v1.0 before this revision or
+#                           ver1.0-31337+g4c1c21d if there is tag ver1.0
