=====

* Include support for more tests in the makefile.

* Maintain global TODO document by automatically extracting ## TODO:
comments from all of the scripts.  Update all functions to include
compatibility notes (aka missing features) in these comments.  Some
function specific notes in matcompat/compat.dat belong in TODO comments.

* make doc subdirectory for each script directory for ancillary docs and 
use install to put them in a reasonable place; ideally they should 
piece-wise construct a manual describing the available functions and
the relationships between them.  Alternatively, each package could have
an index.html which is installed in /usr/share/doc/octave-forge/package.html

* Use ../../Makeconf for engine functions.  Engine functions are not
installed; figure out how and where to install them (presumably as
a shared library in /usr/local/lib).

* extra/ver20 is not presently installed, but it could be if we detected
an octave version of 2.0.x rather than 2.1.x

* nonfree/gpc uses its own configure script and build process

* consider -enable/disable on a package by package basis as a way
to override the NOINSTALL files on some of the directories; maybe
just an -enable-all option?

* how to "chmod a+x octinst.sh" from configure? Currently I do it
in the makefile during install.

All functions
=============

* Use texinfo in the function descriptions.  Call makeinfo to preformat 
the descriptions when installing for version 2.0.x.

* Add test and demo scripts for each function.  Should we use
extra/testfun, or should we use name_test.m and name_demo.m?
	
* Replace x(find(cond)) with x(cond) since it is faster and cleaner.
Remove unwind_protect blocks for do_fortran_indexing, since most
instances will be covered by this.  For the 2.0.x version of the 
function you will need to either use find() or set prefer_zero_one_indexing
to 1 inside an unwind_protect block.

* For 2.0.x, be sure x(:,ones(n,1)) uses prefer_zero_one_indexing = 0.

* Replace max(max(x)) with max(x(:)), and so on for min, sum, etc.
This will be faster when using version >2.1.31

Specific functions
==================

* Use newer version of QHull.

* Define idx=lookup(table, y, k) which guarantees that the window of width
k will lie fully within the table.  Maybe this is equivalent to
	lookup (table (1+k : length (table)-k), y) + floor(k/2);

* Consider defining lookup as
	table(idx) < y <= table(idx+1)
rather than
	table(idx) <= y < table(idx+1)
This could be a compatibility issue.

* Maybe recode lookup() in C++.  Use binary search for small y and 
sort-merge for large y.

* merge plot/dhbar with Octave's bar; add preference variable for 'filled';
add control for bar width

* split FIXES/freqz into FIXES/freqz and FIXES/freqz_plot so that a 
non-gnuplot based plot package can override freqz's plot.

* Give ginput a "number of inputs" parameter.  Redefine gtext as an
m-file which calls ginput(1) to get the text location.

* Give ginput a rubber-banding facility, maybe with number of inputs =
-1 ?  Redefine gzoom as an m-file which calls ginput(-1) to get the
region.

* Have ginput return the key/mouse button used to exit.
