+The roundup mail gateway may be called in one of two ways:
+ . with an instance home as the only argument,
+ . with both an instance home and a mail spool file, or
+ . with both an instance home and a pop server account.
+
+PIPE:
+ In the first case, the mail gateway reads a single message from the
+ standard input and submits the message to the roundup.mailgw module.
+
+UNIX mailbox:
+ In the second case, the gateway reads all messages from the mail spool
+ file and submits each in turn to the roundup.mailgw module. The file is
+ emptied once all messages have been successfully handled. The file is
+ specified as:
+ mailbox /path/to/mailbox
+
+POP:
+ In the third case, the gateway reads all messages from the POP server
+ specified and submits each in turn to the roundup.mailgw module. The
+ server is specified as:
+ pop username:password@server
+ The username and password may be omitted:
+ pop username@server
+ pop server
+ are both valid. The username and/or password will be prompted for if
+ not supplied on the command-line.
