Re: Crazy idea - replace RCS backend with ClearCase...!!!

[Julian Gosnell]

OK,

That makes my life harder....

I reiterate the same question though:

Does this library represent the only interface between the data that it
encapsulates and the cvs binary ?

I guess I might now be looking at writing a library instead of some
scripts....

Thanks again,


Jules
