Hi Albert,

So this is a wrapper on top of PyTables to implement load() and  
save()? Neat.

Obviously if you're installing PyTables, you can do a lot better and  
organize your data hierarchically without the messiness of Matlab  
structures, walk the node tree, all kinds of fun stuff, but if  you're  
an expatriate matlab user and just want to save some matrices... this  
is great. Notably, that was one of my gripes about ipython+numpy+scipy 
+matplotlib when I first came from Matlab.

I think you should send a message to the PyTables list, ask Francesc  
if he thinks it has a place in PyTables for it as a 'lite' wrapper or  
something, for people who need to save data but don't need/are  
intimidated by all the features that PyTables provides.
