In fact I just want to create a wrapper around rcs that offers a 
different user interface and maybe adds some highlevel features not 
implemented in rcs. I'm not yet sure about which features of rcs I will 
use. At least the basics like checking in/out, locking, showing history 
and diffs.

I didn't survey much of there scripts as I first wanted to know if there 
is something like an API instead of the command line interface.

Of course for example to provide a different presentation of the log 
history, I could just parse the rcs file. But I thought there might be a 
more convinient way by using functions of rcs that do the parsing for me.
And for the user input (e.g. checking-in a file) I'd to avoid making an 
external call to the rcs binaries.
