-
-// ENVIRONMENT
-//
-// This program expects the environment variable C<HOME> to be set, and
-// executes a change directory to the contents of it before starting.
-//
-// This program expects C<MAILDIR> to be set, and delivers any bulletins
-// that it finds into this maildir.
-//
-// If C<VUSER> is set, a local bulletin directory is searched as above.
-
-// FILES
-//
-// The following control files are used:
-//
-// =over 8
-//
-// =item F<global-bulletin-dir>
-//
-// This specifies the bulletin directory for all domains.
-//
-// =item F<bulletin-dir>
-//
-// This specifies the bulletin (sub)directory for virtual domains.
-//
-// =back

-// SEE ALSO
-//
-// vmailmgr(7),
-// checkvpw(8),
-// configuration.html
-
-// NOTES
-//
-// If either the global or local bulletin directories do not exist, they
-// are silently ignored without failing.
