grind
grind: vt. 1. [MIT and Berkeley] To prettify hardcopy of code,
especially LISP code, by reindenting lines, printing keywords and
comments in distinct fonts (if available), etc. This usage was
associated with the MacLISP community and is now rare;
prettyprint was and is the generic term for such
operations. 2. [UNIX] To generate the formatted version of a
document from the nroff, troff, TeX, or Scribe
source. 3. To run seemingly interminably, esp. (but not
necessarily) if performing some tedious and inherently useless
task. Similar to crunch or grovel. Grinding has a
connotation of using a lot of CPU time, but it is possible to grind
a disk, network, etc. See also hog. 4. To make the whole
system slow. "Troff really grinds a PDP-11." 5. `grind grind'
excl. Roughly, "Isn't the machine slow today!"
