More shots inside the package

UI21DEB is a DOS real mode deBUGGER focusing on file I/O activity
performed via INT $21. While the world is already full debuggers
("Insight" real mode debugger by Oleg & others, FreeDOS DEBUG, G[R]DB,
"deb" by Japheth, OlyDbgr (does it really work in DOS ?), WATCOM's "WD"
(seems not to work in DOS either ?), "SD" by Narech Koumar (dropped
with DOS/32A version 9.xx ?), and last but not least the famous
FTE-debugger), UI21DEB has some unique features, OTOH it also lacks
some features known from the other debuggers, so NO, it doesn't attempt
to obsolete them all, see "Comparison" below for details. While a
debugger is usually a tool for developers and advanced users only,
UI21DEB has some features making it useful to "average" users as well,
see "For users" below.
