      long_description="""
sla provides an interface to slalib, a set of routines for celestial coordinate and time 
manipulations written by Pat Wallace. The Python sla interface uses this to provide a few 
convenient routines for Python scripts. These provide light travel time corrections good to 
about 50 microsecs amongst other things. It is not a complete interface to all sla routines.
