mex function online help text

[Dan McMahill]

Hello,

I'm using octave-3.2.4.  I have a compiled mex function which has been
installed to:
${prefix}/libexec/octave/3.2.4/site/oct/i686-pc-linux-gnu/wcalc-1.1/
bars_calc.mex

It works.  When I run octave, bars_calc() is available as a function
and does what I expect.

However, the online help does not  work.

octave-3.2.4:1> help bars_calc
error: help: `bars_calc' is not documented

yet I do have this file installed:
${prefix}/libexec/octave/3.2.4/site/m/wcalc-1.1/bars_calc.m

The top several lines of bars_calc.m look like the following.  The
first "%" line is the first line of the file.

%BARS_CALC        - Self and mutual inductance of a pair of parallel
rectangular bars
%
%  SYNOPSIS
%
%  [L1, L2, M, k] = bars_calc(a, b, l1, d, c, l2, E, P, l3, freq)
%
%  PARAMETERS
% ....

Any idea what I'm doing wrong?

Thanks
