|
# Modified slightly for ImageMagick by Bob Friesenhahn, 1999
|
|
#
|
|
# Used to create a copy of the a directory tree that has links for all
|
|
# non- directories. If you are building the distribution on more than
|
|
# one machine, you should use this script.
|
|
#
|
|
# If your main 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.
