r15785 - /1.3/status.py -- April 19, 2012 - 23:09

New Revision: 15785

URL: http://svn.gna.org/viewcvs/relax?rev=15785&view=rev
Log:
Created the _det_install_path() status singleton method for better 
determining the install path.

This will be used for the Mac OS X applications whereby the current logic of 
using sys.path[0]
fails miserably!
