Guppy-PE
Guppy is an umbrella package combining Heapy and GSL with support utilities such as the Glue module that keeps things together.
The name guppy was chosen because I found it in a backward-dictionary as a word ending with py and I thought it was cute enough and that it would not so likely conflict with some other package name. It was to be a general name since all kinds of packages should fit under this top level name.
The name guppy-pe is because there was another project named guppy in Sourceforge when I was about to register guppy. The other guppy was not in Python, so I added -pe which means Programming Environment. The Python package is just guppy.
