support for configuration options from command line

[edipal]

I think it would be nice to be able to overwrite some configuration options from command line. For example it might be useful when you build locally to use a different options.

Another possibility could be to add support for specifying a different configuration file from command line.

jgitver principle make the git history/data the truth of the computed version, allowing command line switches change the previous principle.

I am not against opening the system but can you explain the use case/need before?

i would like, in some cases (short features/bugfixes), to not include anything from the branch name in the version id
but i think we can do this using regex (when we include a certain marker in the branch name) - so we can distinguish between the two cases
