revision number less than 1.1

[Petr Aubrecht]

Hello,

I started to use CVS and have one small trouble.

I would like to use revision numbers less than 1.1, let say 0.0.1, or 1.0.1
etc. It allows me to make the revision number the version number of the
software (is it bad idea?). Now, cvs commit -r 0.1 doesn't work.

Is there also a way how to store all histories at once? I would like to see
what has changed in all project, not for single file.

I have read a lot of documentation, but didn't find any answers.

Thanks,
Petr
