   1"""
   2This modules contains default config values and basic wrapper for ConfigParser.
   3New config options should be added to the dictionary below, along with 
   4appropriate defaults. Runtime configuration is done through the config file at
   5/etc/logparse/logparse.conf (default) or the path specified in the "--config"
   6argument. The file uses the INI syntax, with general options being declared in
   7the [logparse] section and parser-specific options declared in their own
   8sections.

  10This module provides the following methods:
  11    - `loadconf()`: set up ConfigParser and process config file
