"""
Genetrack file transformer. 

The program may be invoked in multiple ways. As a standalone script::

    python hdf_loader.py

As a python module::

    python -m genetrack.scripts.hdf_loader

Or in other python scripts::

>>>
>>> from genetrack.scripts import hdf_loader
>>> hdf_loader.transform(inpname)
>>>

Run the script with no parameters to see the options that it takes.

**Observed runtime**: insertion rate of 6 million lines per minute
