RCS does not use MySQL or any other SQL engine.

I am looking to use a SQL backend for RCS.

RCS is a specific tool unlike source control management (SCM), it is a 
text file database. There are no SQL based RCS implimentations that I know 
of, that was why I asked in the first place.



A RCS file is comprised of:

  meta data bout the state of the file
  current source
  0..N reverse deltas from current source
  meta data about the various revisions represented,
   including who, when, why.

ex:

head    1.2;
access;
symbols;
locks; strict;
comment @# @;


1.2
date    2005.07.31.20.05.02;    author jpyeron; state Exp;
branches;
next    1.1;

1.1
date    2005.07.07.05.20.31;    author jpyeron; state Exp;
branches;
next    ;

desc
@@
