Try "import ni" in the script for older Pythons. This worked fine
for Grail until other aspects of the code required 1.5. Make sure the
__init__.py files contain nothing by comments and docstrings.

Use regex and more backslashes. These are convenient, but not
required for functionality.

Not required for functionality.

Don't use assert; write a function that does the same thing. This
is trivial, but you're welcome to steal the Assert module from Grail
if it's too much typing. ;-)
