You can either commit the changes with the "-m <msg>" or with the "-F <file>" switch. In your case I'd suggest the latter:

1. regenerate your files and include a step that generates
    a commit message and stores that in a file, say "commit.msg".
2. review the changes
3. add all your files (except for "commit.msg", of course)
4. commit:
      $ git commit -F commit.msg

The other way would be the -m switch, but then you'd have to supply the message by yourself somehow: $ git commit -m "These files were generated at ..."
