- # Used to create a copy of the a directory tree that has links for all non-
- # directories (except those named RCS). 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
- #
- # Note: does not link files beginning with "." Is this a bug or a feature?
- #
- # Improvements over R3 version:
- # Allows the fromdir to be relative: usually you want to say "../dist"
- # The name is relative to the todir, not the current directory.
- #
- # Bugs in R3 version fixed:
- # Do "pwd" command *after* "cd $DIRTO".
- # Don't try to link directories, avoiding error message "<dir> exists".
- # Barf with Usage message if either DIRFROM *or* DIRTO is not a directory.
