+# A note on PR and PV:
+# PV is the package version, and PR is the package revision from the OE
+# perspective. So if we need to modify meta-ettus to fix a version of UHD, but
+# UHD itself is not changing, then we start incrementing the revision. We can
+# leave out PR otherwise, but we can't retroactively take out PR because that
+# would look like we're going back on the version numbers.
+# General guidelines:
+# - The first time we release a UHD + OE version, we put the version number into
+#   PV, and remove PR if it's set.
+# - Pre-releases to that use the `+foo` notation to append something to the
+#   version number, such as `+rc1` or `+git5`.
+# - If we need to modify the OE package info after tagging a UHD release, and
+#   we've already published a version within OE, we start incrementing PR as in
+#   r1, r2, etc.
