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. See also farm.
