programming languages, it
 seems desirable that the name of a package for a Python module contains
 the word @code{python}.
 
-Some modules are compatible with only one version of Python, others with both.
-If the package Foo compiles only with Python 3, we name it
-@code{python-foo}; if it compiles only with Python 2, we name it
-@code{python2-foo}. If it is compatible with both versions, we create two
