How to: get list of modules in a package

Thanks, Peter.  So the fact I didn't see any solution was not due to my lack 
of knowledge.  I thought I should ask and maybe someone would point out an 
elegant solution that was just beyond my own grasp of Python.

os.listdir() would not work in the general case, but it's good enough in my 
limited case.  The package is well-determined and it's always a directory. 
Even if I will change that some day, there will always be another equivalent 
for the os.listdir.

So thanks again, I can confidently go and implement a solution based on 
os.listdir.
