  Parton Distribution Functions (PDFs) are essential non-perturbative inputs
for calculation of any observable with hadronic initial states. These PDFs are
released by individual groups as discrete grids as a function of the Bjorken-x
and energy scale Q. The LHAPDF project at HepForge maintains a repository of
PDFs from various groups in a new standardized LHAPDF6 format, as well as older
formats such as the CTEQ PDS grid format. ManeParse is a package that provides
PDFs within the Mathematica framework to facilitate calculating and plotting.
The program is self-contained so there are no external links to any Fortran, C
or C++ programs. The package includes the option to use the built-in
Mathematica interpolation or a custom cubic Lagrange interpolation routine
which allows for flexibility in the extrapolation (particularly at small x
values). ManeParse is fast enough to enable simple calculations (involving even
one or two integrations) to be easily computed in the Mathematica framework.
