configuration parameters for perl module in rlm_perl

Hi list, is there are recommended way to pass configuration parameter to a rlm_perl module? My rlm_perl module, would need to have additional configuration parameters. I would like to avoid having the perl module read an additional configuration file. Is there a possibility to add such paramters somewhere in the freeradius config like in /etc/freeradius/modules/perl and than have the perl module access these parameters? Thanks a lot and kind regards Cornelius
