# testSpecVersion - check if SPEC_VERSION values for an unpublished
# extension branch meet the requirement of being 1.
#
# Usage: textSpecVersion.py [-branch branchname] [-registry file]
#
# Checks for an XML <extension> matching the branch name specified
# on the command line, or the current branch if not specified.
#
# If not found, the branch is not an extension staging branch; succeed.
# If found, but extension is disabled, don't run the test; succeed.
# If found, and extension SPEC_VERSION has a value of '1', succeed.
# Otherwise, fail.
