+## Notes

+PAM authentication: it allows to authenticate IRC users from the system in
+Unix/Linux. The user that executes irgramd must have permissions to use PAM
+(e.g. in Linux be in the shadow group or equivalent).
+The dependency is totally optional, if not use, the module pyPAM is no
+needed.
