/***********************************************************************
Split a binary file into pieces of a specified (or default) size.
Usage:
bsplit [[-nnn] [-] filename]
A -nnn bytecount option sets the split piece size for subsequent
files. Stdin is assumed if a bare - is given, or if no files are
specified. Multiple filenames may be specified.
No check is made to see whether the output files (named with the input
file name and the suffixes "-001", "-002", etc.) exist.
[29-Aug-1990] Nelson H. F. Beebe
