    _______________________________________________________

Details:

The package optim-1.0.12 contains a function fminsearch.m which is obviously
an attempt to provide functionality along the lines of Matlab's "fminsearch". 
The Octave version, however, contains a "grad" argument that is not present in
Matlab's calling sequence.  I suggest deleting that argument to make the call
more similar to Matlab's.  The "grad" argument has no function in the
Nelder-Mean minimization scheme that fminsearch uses.  I attached a diff -c
file for the change I have in mind.
