Notes on  HAND-HACKING 

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, 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.
