X    ecusz.c - X/Y/ZMODEM send program
X  Derived from public domain source by Chuck Forsberg, Omen Technologies
X  Adaptation for ecu 1989 [e-mail]
X
X    Usage:    ecusz [-X -Y -Z] [-12+abdefkLlNnquvwy] [-] file ...
X        (Y) = Option applies to YMODEM only
X        (Z) = Option applies to ZMODEM only
X        a (ASCII) change NL to CR/LF
X        b Binary file transfer override
X        f send Full pathname (Y/Z)
X        k Send 1024 byte packets (Y)
X        L N Limit subpacket length to N bytes (Z)
X        l N Limit frame length to N bytes (l>=L) (Z)
X        n send file if source newer (Z)
X        N send file if source newer or longer (Z)
X        o Use 16 bit CRC instead of 32 bit CRC (Z)
X        p Protect existing destination file (Z)
X        r Resume/Recover interrupted file transfer (Z)
X        q Quiet (no progress reports)
X        u Unlink file after transmission
X        w N Window is N bytes (Z)
X        y Yes,overwrite existing file (Z)
X        @file reads a list of filenames from 'file'
