/*
* rcsarch.h - in-memory RCS file RcsArchive
*
* Classes defined:
*
* RcsArchive - parsed, in memory copy of RCS file
* RcsList - string lists for locks, symbols, access, branches
* RcsRev - all information about a revision
* RcsChunk - a pointer/length back into the RCS file for @ text
* RcsText - an allocated string with its strlen().
*
* Public methods:
*
* RcsArchive::RcsArchive() - initialize RcsArchive
* RcsArchive::~RcsArchive() - free everything allocated to RcsArchive
* RcsArchive::AddRevision() - chain a revision onto the archive's list
* RcsArchive::FindRevision() - find a revision on the chain
* RcsArchive::NextRevision() - conveniently follow the rev's next pointer
* RcsArchive::Parse() - parse the whole RCS archive
* RcsArchive::FollowRevision() - compute successor to current rev
*
* RcsList::RcsList() - append new list member onto chain
*
* RcsText::Save() - copy text into a new buffer
*
* RcsChunk::Save() - save offset/length pointers of @ block
*
* Note that just about everyone looks at these structures. Only
* the routines above should update them, though.
*
* History:
* 5-13-95 (seiwald) - added lost support for 'branch rev' in ,v header.
* 12-17-95 (seiwald) - added support for 'expand flag' in ,v header.
* 2-18-97 (seiwald) - translated to C++.
