# This script is used to check in sources that previously was under RCS or  #
# no source control system.				  		    #
#									    #
#	Usage: rcs-to-cvs repository 					    #
#									    #
# The repository is the directory where the sources should		    #
# be deposited. 
#									    #
# checkin traverses the current directory, ensuring that an 		    #
# identical directory structure exists in the repository directory.  It	    #
# then checks the files in in the following manner:			    #
#									    #
#		1) If the file doesn't yet exist, check it in 		    #
#			as revision 0.1					    #
#									    #
# The script also is somewhat verbose in letting the user know what is	    #
# going on.  It prints a diagnostic when it creates a new file, or updates  #
# a file that has been modified on the trunk.		   		    #
