#
# If $1 contains "RCS" in symbolic link name, remove it in destination symbolic
# name. This has the effect of making a symbolic link in a tree that does not
# have RCS directories. This is a step we need to do to make symbolic links in
# cvs tree to reflect the symbolic link in the ptools tree.

# If $1 is a symbolic link and DO NOT CONTAIN "RCS" in file name, make the
# same link in destination tree. This preserves any symbolic links to
# directories.

# if directory links, don't strip ../, else ,v links, do strip
