How hard is it to use the 3 most routine commands of sccs which are
admin (to create the archive), get (to extract versions from the 
archive), and delta (to return a version to the archive)?  I must
admit that I have not used sccs to its full capability but I have
done some significant programming projects with it.  It sure beats
the heck out of making filename.old's and forgetting which version
it was.  Especially if you have many files in your application.  As
far as a front end goes it would be very simple to make a shell 
script to handle the basics.  To use the example cited above with
the admin command and the enforced "s.":

# sccs.sh
admin -i$1 s.$1
<EOF>

Command line % sccs.sh lang

You could even have the shell script remove the lang file if you 
felt that confident that the archive had been properly established.
And you could add fancy prompts to ask you if you wanted to remove
it etc.

Many Unix commands seem to vary in their state of what I might 
consider to be completeness.  However, I believe that this is
a symptom of having many contributors to a robust operating 
system.  I find the advantages far outweigh the disadvantages.
