#
# Desc: Adds support cvs targets within your Makefile.  
#
#       Branching and releasing relies on you using the following
#       version format:
#         MAJOR.MINOR.POINT
#       where MAJOR is the major version number, MINOR is the minor
#       version number and POINT is the point release number.
#
#       Targets:
#		* update
#			performs a cvs update
#
#		* commitlog
#			Generates a ChangeLog template with the modifed,
#			added and removed files and opens it up for editing.
#  			This is not normally used directly, but is instead
#			called by commit.  It is usefull however if you want
#			to document the work you have done, but don't want to
#   			commit just yet.
#
#		* commit
#			performs a cvs commit after first performing a cvs
#			update and generating a commit log.
#
#		* cvs-rm FILES="file1 file2 ..."
#   		  	 removes a file or files specified by the FILES
#			 variable from the file system and from cvs.  It will
#			 interactively ask you to confirm the file removal,
# 			 unless the file does not exist on the file system.
#
#		* make cvs-add FILES="file1 file2 ..."
#   		       	 adds a file or files specified by the FILES variable
#			 to cvs.
#
#		* branch-major
#			creates a branch based on the major version number, 
# 			increments the major version number, sets the minor
#			and point versions to zero and checks out the branch
#			into a new directory.
#
#		* branch-minor
#			creates a branch based on the minor version number,
#			increments the minor version, sets the point version
#			to zero number and checks out the branch into a new
#			directory.
#
#		* release
#			performs a cvs update, followed by a distcheck, then
#			creates a release for the current version,
#			increaments the point release number and checks out
#			the release into a new direcory
#
#		* quick-release
#			same as release, but distcheck is not performed
#
# ChangeLog:
# 2005-06-28	Tom Howard	<[e-mail]>
# 
#	* Now checks for awk instead of gawk
