# NOTE: The read and echo method may not always have the desired result for pkgver() depending on the tree
# One of the following cut commands will work for the case where the other git version gymnastics don't.
# Uncomment the desired line, according to the desired version string delimited by "."
# (and if so, comment out both the read and echo lines below it)
# At the time of writing it is once again fine the way it is for both main and tag checkouts

# If you would like to build a release tag instead of main, uncomment and edit the "git checkout" line within the pkgver() function below.
