"""
Fortran namelist parser. Converts nameslists to python dictionaries.

Should be fairly robust. Cannot be used for verifying fortran namelists as it
is rather forgiving.

Error messages during parsing are kind of messy right now.

Usage
=====

>>> from namelist import namelist2dict
>>> namelist_dict = namelist2dict("fortran_list.txt")

Can deal with filenames, open files and file-like object (StringIO).


Works with Python 2.7 and has not further dependencies.
