hand-hacking: n. 1. [rare] The practice of translating hot
spots from an HLL into hand-tuned assembler, as opposed to trying
to coerce the compiler into generating better code. Both the term
and the practice are becoming uncommon. See tune, bum, by
hand; syn. with v. cruft. 2. [common] More generally, manual
construction or patching of data sets that would normally be
generated by a translation utility and interpreted by another
program, and aren't really designed to be read or modified by humans.
