quixote users,

i'd like to announce the release of version 0.3 of DeltaStat, a
program that performs statistical calculations on data from proteomics
experiments.  here is the home page:

http://deltastat.sourceforge.net

DeltaStat is one of the few open source applications that uses
quixote's WAF, web application framework (at least from what i found,
and i looked.. hard).  since it took me a while to grasp some of the
concepts of quixote, i'm hoping this will help people along who are
new to programming with quixote.

i chose to make DeltaStat a web application because it has a number of
dependencies.  i originally had used plain cgi for it, but as you can
see from the source of versions 0.2.x, it became quite messy.  i
initially tried using quixote's WAF then became discouraged by the
lack of a variety of examples.  then i decided to use nevow, an idea
which i soon dropped.  part of the reason i chose python was because
of it's readability, and nevow is unnecessarily hard to read.  i went
back to quixote, even more determined.  examining Collar's cvs by
titus brown was quite helpful.

during the conversion from plain cgi to quixote, i tried to keep the
programming logic away from the presentation logic, and the
presentation logic away from the presentation, following the
model-view-controller framework.  i've separated my program into three
main files (so far): deltastat.py - the programming logic, forms.ptl -
mostly presentation logic, and templates.ptl - the presentation.  i'd
be interested in hearing how other people organize their projects.

for DeltaStat's forms, i used the method in quixote/demo/widgets.ptl.
i was wondering why there are two different ways.  is the way shown in
quixote/demo/forms.ptl the newer or cleaner way?  i'm sure there are
plenty of cases where i could have used quixote more efficiently.
please let me know if you see any.

also, let me know if you'd be interested in contributing to this
project:
