I would still require a brief description.

It should be in the same file.  Its hard enough tracking down code
across multiple files, without the necessity of looking for the
documentation in some other place.

I would make a standard form of comments where there is a keyword before
each piece of information.  Then a fairly simple program can have
access.  We use a scheme devised at HP which creates a header like the
following, along with a revision list:
% File:         MINI-SUPPORT.SL

% Revisions:
% 9-Mar-84 15:03:40  (Robert Kessler)
%  Added fluid definition of !*writingfaslfile, and modified
%   rule-define, so it does a boundp check before accessing the value of
%   the variable.  For strange reasons, this a call to an undefined
%   function if the compiler wasn't loaded.
% 27-Feb-84 11:58:47 (Robert Kessler)
%  Added Legal-single-char to check to see if a keyword is an
%   alphanumeric character.  We do not want to make an alphanumeric
%   character a keyword.  This would make words with that letter in it
%   invalid.  Therefore, if the grammar definer makes something a
%   keyword (like 't), it must be separated by other delimiters.
