Tyler,

I'm not convinced we want to do that.  I did it to ensure that all the
environment settings were done properly and bullet proof.  But the
alternative is to provide csh and bash versions of scripts that the user
can source to accomplish the same.   Note, it isn't terribly hard to wrap
everything.  I just use a generic wrapper script for everything.  It looks
like this:

#!/bin/sh

TARGET=$0

if [ "`basename $TARGET`" = "env_cover.sh" ] ; then
   echo "This script is not intended to be run directly."
   exit 1
fi

OPENEV_HOME=`dirname $TARGET`
OPENEV_HOME=`dirname $OPENEV_HOME`

# Setup Environment Variables for OpenEV

PROJ_LIB=$OPENEV_HOME/share/proj
GEOTIFF_CSV=$OPENEV_HOME/share/gdal
GDAL_DATA=$OPENEV_HOME/share/gdal
PYTHONHOME=${OPENEV_HOME}
PYTHONPATH=${OPENEV_HOME}/pymod:${PYTHONPATH}
LD_LIBRARY_PATH=${OPENEV_HOME}/lib:${LD_LIBRARY_PATH}
PATH=${OPENEV_HOME}/bin:$PATH
LC_NUMERIC=C

export PYTHONHOME PYTHONPATH LD_LIBRARY_PATH PATH PROJ_LIB GEOTIFF_CSV LC_NUMERIC GDAL_DATA

$OPENEV_HOME/bin/`basename $TARGET` $@
