# 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 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. |
