You may want to try out ipython 
(http://www-hep.colorado.edu/~fperez/ipython/). Instead of doing 'import', you 
can cd to the definition directory and type 'run leo_ncd3d'.  This executes 
the file in the current namespace, so any changes made to the source take 
effect immediately.  That's typically my approach, and for most single-level 
modules it works well.  If you have a complex package with nested structure, 
ipython offers a 'dreload' version of reload which helps doing recursive 
reloads.

Best regards,

Fernando.
