# A simple wrapper for global logging / debug flags, rather than the
# less efficient per-file bit array system.
# Usage:
#   from debug import Debug
#   Debug.set('DISABLE_TAXIMETER', True)
#   ...
#   if Debug('DISABLE_TAXIMETER'):
#       ... etc ...
# All debug flags default to false. This can be changed with Debug.set_default
