crunch 1. vi. To process, usually in a time-consuming or complicated
   way. Connotes an essentially trivial operation that is nonetheless
   painful to perform. The pain may be due to the triviality's being
   embedded in a loop from 1 to 1,000,000,000. "FORTRAN programs do mostly
   {number-crunching}." 2. vt. To reduce the size of a file by a
   complicated scheme that produces bit configurations completely unrelated
   to the original data, such as by a Huffman code. (The file ends up
   looking something like a paper document would if somebody crunched the
   paper into a wad.) Since such compression usually takes more
   computations than simpler methods such as run-length encoding, the term
   is doubly appropriate. (This meaning is usually used in the construction
   `file crunch(ing)' to distinguish it from {number-crunching}.) See
   {compress}. 3. n. The character `#'. Used at XEROX and CMU, among other
   places. See {{ASCII}}. 4. vt. To squeeze program source into a
   minimum-size representation that will still compile or execute. The term
   came into being specifically for a famous program on the BBC micro that
   crunched BASIC source in order to make it run more quickly (it was a
   wholly interpretive BASIC, so the number of characters mattered).
   {Obfuscated C Contest} entries are often crunched; see the first example
   under that entry.
