+ * RMAIL -- UUCP mail server.
+ *
+ * This program reads the >From ... remote from ... lines that UUCP is so
+ * fond of and turns them into something reasonable.  It then execs sendmail
+ * with various options built from these lines. 
+ *
+ * The expected syntax is:
+ *
+ *	 <user> := [-a-z0-9]+
+ *	 <date> := ctime format
+ *	 <site> := [-a-z0-9!]+
+ * <blank line> := "^\n$"
+ *	 <from> := "From" <space> <user> <space> <date>
+ *		  [<space> "remote from" <space> <site>]
+ *    <forward> := ">" <from>
+ *	    msg := <from> <forward>* <blank-line> <body>
+ *
+ * The output of rmail(8) compresses the <forward> lines into a single
+ * from path.
+ *
+ * The err(3) routine is included here deliberately to make this code
+ * a bit more portable.
