[Gmath-devel] Re: scientific python

[Hassan A. <au...@cr...>]

 Yappa di doo or more humanly agreed.

 We need to build a database of such stuff. Anyone care to do that?
 
 Any thoughts about how to do it? I need some kind of tree like list 
of packages for numerical python (xml?) that could be parsed by 
python. It would be placed on GmatH web page (hidden) and parsed by 
GmatH to check where packages are and what version. Something like:

 all = [list of all packages]
 NumericalPy, $version, $rpm_address/None, $tar.gz address/none
 Cephes,	$version ......

 Then we add a widget that would have a shipped list of packages but 
could "update" the list and packages from the web by fetching this 
tree-like file.

 This should be easy to do but needs a maintainer other than me.

 Volunteers anyone?
