link farm: n. [Unix] A directory tree that contains many links
to files in a master directory tree of files. Link farms save space
when one is maintaining several nearly identical copies of the same
source tree -- for example, when the only difference is
architecture-dependent object files. "Let's freeze the source and
then rebuild the FROBOZZ-3 and FROBOZZ-4 link farms." Link farms
may also be used to get around restrictions on the number of `-I'
(include-file directory) arguments on older C preprocessors.
However, they can also get completely out of hand, becoming the
filesystem equivalent of spaghetti code.
