gitdesc.sh assumes tag will have format v#.### and will return major version, minor version, and micro version depending on command. gitdesc.sh will also add tag revision and HEAD commit if tag is not equal to HEAD. So lrzip version may appear as `#.###' or `#.###-R-#######' where `R' is count of commits since last tag. usage gitdesc.sh command [-r] where command is one of: all - entire git describe commit - commit, omitting v tagrev - tag revision count major - major release version ninor - minor release version micro - micro release version + [tag release count-HEAD commit] version - M.mic -r -- get release tag only
