/*
 *  lmail: local mail delivery agent
 *
 *  Stephen Trier
 *  January 12, 1990
 *
 *  Version 1.0   1/12/90  "cat" command.  Uses binary mode for I/O.  Need
 *     a sensible way to handle ^Z.  Uses standard MS-DOS wildcard filespecs.
 *
 *  Version 1.1   3/27/90  Convert from "cat" into "lmail".  Complete
 *     rewrite.  This version is fast, but may thrash if several recipients
 *     are specified on the command line.
 *
 *  This program is in the public domain.
