=head1 check_cvs.pl
Script to check the integrity of the Repository
=head1 SYNOPSIS
check_cvs.pl
=head1 DESCRIPTION
This script will search through a repository and determine if
any of the files in it are corrupted.
Please do not run this script inside of the repository itself,
it will cause it too fail.
Also it currently can only be run over the entire repository,
so only point your CVSROOT at the actual CVSROOT.
=head1 OPTIONS
There are no options.
=head1 EXAMPLES
setenv CVSROOT /release/111/cvs
# To see more verbose output
setenv CVSDEBUGEDIT 1
check_cvs.pl
=head1 SEE ALSO
None

# To decide if a file is broken or not. The algorithm is:

# and continue processing other files.
# - If that succeeds we have a list of revisions.
# b) For Each revision try to retrieve that version
# - If that fails the file is broken, save the fact
# and continue processing other files.
# c) Continue on
#
# PARAMETERS :
# $file - The file to look at.
#
# GLOBALS :
# NONE
#
# RETURNS :
# NONE
#
# COMMENTS :
# We have to handle Attic files in a special manner.
# Basically remove the Attic from the string if it
# exists at the end of the $path variable.

# NAME :
# find_interesting_revisions
#
# PURPOSE :
# CVS stores information in a logical manner. We only really
# need to look at some interestin revisions. These are:
# The first version
# And the last version on every branch.
# This is because cvs stores changes descending from
# main line. ie suppose the last version on mainline is 1.6
# version 1.6 of the file is stored in toto. version 1.5
# is stored as a diff between 1.5 and 1.6. 1.4 is stored
# as a diff between 1.5 and 1.4.
# branches are stored a little differently. They are
# stored in ascending order. Suppose there is a branch
# on 1.4 of the file. The first branches revision number
# would be 1.4.1.1. This is stored as a diff between
# version 1.4 and 1.4.1.1. The 1.4.1.2 version is stored
# as a diff between 1.4.1.1 and 1.4.1.2. Therefore
# we are only interested in the earliest revision number
# and the highest revision number on a branch.
#
# PARAMETERS :
# @revisions - The list of revisions to find interesting ones
#
# GLOBALS :
# NONE
