The Jargon File (version 4.4.7, 29 Dec 2003):
kluge up vt. To lash together a quick hack to perform a task; this is milder than cruft together and has some of the connotations of hack up (note, however, that the construction kluge on corresponding to hack on is never used). ? I've kluged up this routine to dump the buffer contents to a safe place.?
