++ *
++ * The expected syntax is:
++ *
++ *	 <user> := [-a-z0-9]+
++ *	 <date> := ctime format
++ *	 <site> := [-a-z0-9!]+

++ *	    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.
