config_filter.c

   1 /* config_filter.c: handle hidden or non-configuration files in config dirs.
   2
   3    These functions are called whenever we will parse configuration files to
   4    ensure we are not picking up backups, SCM meta data, package artifacts.
   5    Eventually all config files will have to follow a convention so these
   6    lists of possible exceptions should not have to grow by very much.
