# Used to create a copy of the a directory tree that has links for all
|
|
# non- directories (except those named RCS or SCCS). If you are
|
|
# building the distribution on more than one machine, you should use
|
|
# this script.
|
|
#
|
|
# If your master sources are located in /usr/local/src/X and you would like
|
|
# your link tree to be in /usr/local/src/new-X, do the following:
|
|
#
|
|
# % mkdir /usr/local/src/new-X
|
|
# % cd /usr/local/src/new-X
|
|
# % lndir ../X
