profile /n./  1. A control file for a program, esp. a text
   file automatically read from each user's home directory and
   intended to be easily modified by the user in order to customize
   the program's behavior.  Used to avoid hardcoded choices (see
   also dot file, rc file).  2. [techspeak] A report on the
   amounts of time spent in each routine of a program, used to find
   and tune away the hot spots in it.  This sense is often
   verbed.  Some profiling modes report units other than time (such as
   call counts) and/or report at granularities other than per-routine,
   but the idea is similar.  3.[techspeak] A subset of a standard used
   for a particular purpose.  This sense confuses hackers who wander
   into the weird world of ISO standards no end!
