I think we should spend some time making pegasus-analyzer more user friendly. For example, if you run pegasus-analyzer in the wrong directory, you get:

$ pegasus-analyzer
Traceback (most recent call last):
File "/usr/bin/pegasus-analyzer", line 1529, in <module>
analyze_db(options.config_properties)
File "/usr/bin/pegasus-analyzer", line 990, in analyze_db
output_db_url = connection.url_by_submitdir(input_dir, connection.DBType.WORKFLOW, config_properties, top_dir)
File "/usr/lib64/python2.6/site-packages/Pegasus/db/connection.py", line 94, in url_by_submitdir
raise ConnectionError("Unable to process braindump.txt in %s" % (submit_dir))
Pegasus.db.connection.ConnectionError: Unable to process braindump.txt in /home/rynge/pegasus/gordon-test

It would be nice if you get a real error, with suggestions on how to fix it, instead of a trace. There are probably more errors like this we could improve.
