PyCF is a collection of python modules and programs which can be used to
manipulate glimmer CF data.

Installation
You will need the following packages
* GMT       http://gmt.soest.hawaii.edu/
* proj4     http://proj.maptools.org/
* Numeric   http://www.pfdubois.com/numpy/
* Scientific Python 
            http://starship.python.net/~hinsen/ScientificPython/
* pygsl     http://pygsl.sourceforge.net/
* PySQLite  http://pysqlite.sourceforge.net/
* PyGMT     https://forge.nesc.ac.uk/projects/pygmt/

If your proj4 library is not in a standard location than you need to set
the environment variable PROJ_PREFIX to point to the location where proj4
is installed. You should install PyCF into the GLIMMER_PREFIX, i.e.
./setup.py install --home=$GLIMMER_PREFIX
since some modules query GLIMMER_PREFIX to find data files.

RSL database
If you want to use to RSL plotting methods and programs you need to first
create/get the RSL database. You can download the Peltier's RSL database from 
ftp://ftp.ncdc.noaa.gov/pub/data/paleo/paleocean/relative_sea_level/sealevel.dat
The ascii data set can be converted to the SQLite database using 
PyCF/CF_IOrsl.py --create_db -p sealevel.dat $GLIMMER_PREFIX/share/PyCF/rsl.db

Programs
* create_topo.py - create input topo file
* add_projinfo.py - add project info to existing CF file
* plotCFvar.py - simple plot of CF file
  you can: - specify either a number of variables or a number of times
             that should be plotted
           - set the width of individual maps
           - set lower left corner and/or upper right corner of plot
  check plotCFvar.py -h
