What is it?

	CSSC - a workalike for the Unix SCCS suite

	SCCS - a version control system that comes with Unix systems, \
	it's a bit like RCS.

%page 

Why write it?


	One of the standard features of UNIX -- absent from Linux.

	I needed to use it at work

	Not possible to convert to RCS, because 

		Needed to work with existing software build process

		Can't commit to migration until the result is proven

		Other staff didn't know RCS anyway


%page

History

	Apparently "no" SCCS for Linux.
		Considered writing one - even started!

	Enter MySC (Ross Ridge) http://www.csclub.uwaterloo.ca/~rridge
		Public Domain
		Compiled with GCC 2.4.5 (but not later versions)
		But not interested in patches/bugfixes
		Incomplete
		Not fully compatible with SCCS

	Decision...

Fork the project

Changes to CSSC since the fork

	Extensive!

	Started up a GNU project for CSSC
	Many bugfixes
	Extensive Test Suite
	Command-line compatible with SCCS
	File-format compatible with SCCS
	Almost completely failthful functional replacement
	Documentation - a manual
	Extra tools

	Now on SourceForge - http://cssc.sourceforge.net/

	MySC has moved on somewhat 
%page 

Advantages of CSSC over SCCS


	Binary file support (like Sun SCCS)

	No line length limits

	Often "cleverer" than SCCS

	Self-explanatory error messages
%page

Benefits of CSSC

	Goal of complete compatibility with SCCS
		Because we want Linux to be able to replace Unix 
		Nearly There...

	You can throw away your old Unix box and replace it with Linux
		But keep your existing source code archive and build system

	Old SCCS archives need never die...
%page 

Disadvantages to using SCCS...
%pause

	Only useful to use CSSC if you need to interoperate
	Line-length limits & interoperability
	Crufty shell scripts to make it usable
	Most versions don't support binary files
	Keyword substitution bites you
	SCCS can even corrupt your history file
		But you have to pull the trigger yourself
	Limited support for adding in hooks to support your processes
		Setuid binaries, MR numbers
	SCCS is a pile of rubbish
	There are many better alternatives
