mod vt.,n.
[very common] 1. Short for `modify' or `modification'. Very
commonly used -- in fact the full terms are considered markers
that one is being formal. The plural `mods' is used esp. with
reference to bug fixes or minor design changes in hardware or
software, most esp. with respect to patch sets or a diff.
2. Short for modulo but used
only for its techspeak sense.
