iguration file 'conf'. If name is None, it defaults to the 'default' value in conf. If conf is None, it defaults to the environment variable APPORT_CRASHDB_CONF; if that does not exist, the hardcoded default is /etc/apport/crashdb.conf. This Python syntax file needs to specify: - A string variable 'default', giving a default value for 'name' if that is None. - A dictionary 'databases' which maps names to crash db configuration dictionaries. These need to have at least the key 'impl' (Python module in apport.crashdb_impl which contains a concrete 'CrashDatabase' class implementation for that crash db type). Other generally known options are 'bug_pattern_url', 'dupdb_url', and 'problem_types'. Z
