pyslalib issue

[paulray]

parfile.py has this line from slalib import sla_ecleq, sla_eqecl, sla_eqgal

This does not work for me. I have to change it to from pyslalib.slalib import sla_ecleq, sla_eqecl, sla_eqgal

I think that is because I installed it from github:scottransom/pyslalib, where the package name is indeed pyslalib.

Also pyslalib isn't mentioned in the INSTALL file.

I wonder if it would be best just to pull pyslalib into PRESTO since slalib is already included? Then it would be sure to be installed and the interface would be consistent.
