Requirements:

Requires Python verison 2.5 or greater. 2.7 is preferrable for plotting polygons.

Some operations require that the mangle binary files and scripts are in the $PATH.

Additional python library requirements:

-- numpy >= 1.0.1

-- pyfits >= 3.0.4

If you recieve errors like "Record array does not contain 'columns' attribute," then you need to update your version of pyfits.

For plotting polygons:

-- matplotlib > 1.0

Speeding up mangle.py:

In order to make use of mangle_utils, the library has to first be compiled. The C source code (generated by cython) should have been included with mangle, so all you should need to do is step 2, unless you have changed mangle_utils.pyx, in which case the C needs to be regenerated (step 1).

1. To generate C sources (you should not have to do this), run this: cython -a mangle_utils.pyx

2. to do a full install

    python setup.py install --prefix=/path/to/install
   

   and add /path/to/install/lib/python2.7/site-packages to your PYTHONPATH (use your python version instead of 2.7)

3. To build the mangle_utils library in place instead of doing an install python setup.py build_ext --inplace and add the /mangle subdir of this source to your PYTHONPATH
