Missing allowed 'part' values in commandline help

[kamichal]

Help formed by argparse (bumpversion --help) does not tell what are allowed values for part argument. I mean the 'major', 'minor' and 'patch' (most probably, I believe) .
The help should provide at least minimalistic knowledge required to run given script.
In my case - I knew that there is nice "bumpversion" script but forgot how to call it. I got disappointed trying to find it in the help. I had to run a browser and google for manual, which is insane, because even the README.rst of this project does not list the allowed values.

I had the same issue. I used bumpversion bugfix instead of bumpversion patch, and the result is that I have a scrambled version in setup.py:

version = 'version = '1.0.0''

And a big error message:

$ bumpversion bugfix
fatal: tag 'v1.0.0' already exists

I agree - especially since most people will use them. But please also update the documentation - I had trouble confirming that the name 'patch' was what I wanted. It's in there, but buried, and as a newb it was pretty much the first thing I wanted.
