# Module name   : cc2svn_labeldirs.pl

# Module type   : Makefile system

# Compiler(s)   : Perl

# Environment(s): jats

#

# Description   : Used to process package-versions that are incorrectly

#                 labled - the package has not been labedl up to the root

#                 of the VOB

#

#                 The utility works by scanning the VOB for labeled files

#                 It then determines the full path and will detect paths

#                 that have not been labled.

#

#                 It will then label them

#

#                 The search process is not fast.

#

# Usage:        jats cc2svn_labeldirs 'CC::/VobName/Path::Label'
