+# This file contains the list of FAS email addresses to override for bugzilla.
+# By default we expect that the email address set in FAS corresponds to
+# the bugzilla account of the person.
+# However, some people prefer to use different addresses in FAS and in
+# bugzilla (for example if they want to use their @fedoraproject alias in
+# bugzilla). To support these requests, this file maps FAS email addresses to
+# Bugzilla email addresses where they differ.
