This creates a self-contained python interpreter with numpy (fast matrix math)
and pygrib (GRIB file format support) for NPPDB ancillary manipulation.

It also adds pytables, h5py, and scipy (and their dependencies) for full NPP data manipulation.

It requires
GCC4 with C, C++, Fortran compilers

To build it, 
./shallbethree.sh

To use it
/path/to/ShellB3/bin/python

Additional trim lines currently include
./shallbethree.sh mk_cspp        # core with batch matplotlib, netcdf4, inotify, pylibtiff needed by CSPP projects
                  mk_iasi2fbf    # core + EUGENE, used with polar2grid.iasi to allow iasi2fbf to operate
                  mk_eumetsat    # cspp + EUGENE for EUMETSAT file format access
                  mk_lidar       # requires QT4DIR environment variable, builds with full interactive PyQt4

Note that this package includes patches for EUGENE and PYGRIB
which allow it to use resource paths derived from the location of
sys.executable.
