Gregory Becker fb1874165b Eliminated all calls that relied on finding all packages in the opt directory ... Replaced them all with references to the database Implemented caching in the database. The database now only re-reads data if the database file exists and was changed since this file last wrote to it. Added the installed_db field to the spack instance Left the call to all_specs from testdirectory_layout.py for now.		2015-08-21 17:00:39 -07:00
