you can also just git tag 1.0.0 and git push --tags. Then when you git describe you get a 1.0.0-###-gHASH where ### is the number of commits past 1.0.0 and HASH

you can also just git tag 1.0.0 and git push --tags. Then when you git describe you get a 1.0.0-###-gHASH where ### is the number of commits past 1.0.0 and HASH is the short hash of the last commit (I think). Its really useful for tracking versions across branches and also always having a unique version which points to an exact commit.
