The form of the version string is the closest release version
(5.11.4), the number of commits ahead of that (114) and the SHA1 of
the actual commit. What flavor of consistency are you looking for?

These words don't seem to make sense. Can you translate? The the code
that Tim suggested is the most succinct way to ask Perl if it is at

"perl -v" and performing voodoo.
