-			README for GDBserver
-			  by Stu Grossman
-
-Introduction:
-
-This is GDBserver, a remote server for Un*x-like systems.  It can be used to
-control the execution of a program on a target system from a GDB on a different
-host.  GDB and GDBserver communicate using the standard remote serial protocol
-implemented in remote.c, and various *-stub.c files.  They communicate via
-either a serial line or a TCP connection.
-
-Usage (server (target) side):
-
-First, you need to have a copy of the program you want to debug put onto
-the target system.  The program can be stripped to save space if needed, as
-GDBserver doesn't care about symbols.  All symbol handling is taken care of by
-the GDB running on the host system.
-
-To use the server, you log on to the target system, and run the `gdbserver'
-program.  You must tell it (a) how to communicate with GDB, (b) the name of
-your program, and (c) its arguments.  The general syntax is:
-
-	target> gdbserver COMM PROGRAM [ARGS ...]
-
-For example, using a serial port, you might say:
-
-	target> gdbserver /dev/com1 emacs foo.txt
-
-This tells gdbserver to debug emacs with an argument of foo.txt, and to
-communicate with GDB via /dev/com1.  Gdbserver now waits patiently for the
-host GDB to communicate with it.
-
-To use a TCP connection, you could say:
-
-	target> gdbserver host:2345 emacs foo.txt
-
-This says pretty much the same thing as the last example, except that we are
-going to communicate with the host GDB via TCP.  The `host:2345' argument means
-that we are expecting to see a TCP connection from `host' to local TCP port
-2345.  (Currently, the `host' part is ignored.)  You can choose any number you
-want for the port number as long as it does not conflict with any existing TCP
-ports on the target system.  This same port number must be used in the host
-GDBs `target remote' command, which will be described shortly.  Note that if
-you chose a port number that conflicts with another service, gdbserver will
-print an error message and exit.
-
-Usage (host side):
-
-You need an unstripped copy of the target program on your host system, since
-GDB needs to examine it's symbol tables and such.  Start up GDB as you normally
-would, with the target program as the first argument.  (You may need to use the
---baud option if the serial line is running at anything except 9600 baud.)
-Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'.  After that, the only
-new command you need to know about is `target remote'.  It's argument is either
-a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT
-descriptor.  For example:
-
-	(gdb) target remote /dev/ttyb
-
-communicates with the server via serial line /dev/ttyb, and:
-
-	(gdb) target remote the-target:2345
-
-communicates via a TCP connection to port 2345 on host `the-target', where
-you previously started up gdbserver with the same port number.  Note that for
-TCP connections, you must start up gdbserver prior to using the `target remote'
-command, otherwise you may get an error that looks something like
-`Connection refused'.
-
-Building:
-
-Currently, the only target system supported by the server is Lynx.  To build
-the server for Lynx, make a new copy of the distribution onto a disk that is
-NFS shared with the Lynx system.  Lets say that's in a directory called xyzzy.
-Then, follow these steps under the host system:
-
-	1) cd xyzzy/gdb/gdbserver
-	2) ../../configure --target i386-none-lynx
-
-When that completes, do the following on the Lynx system:
-
-	3) cd xyzzy/gdb/gdbserver
-	4) make CC=gcc
-
-It should build with only a minor complaint about NULL being redefined.  That's
-a LynxOS problem, and can be ignored.
-
-It's also possible that you may have a cross-compiler to Lynx.  In that case,
-you can skip the stuff about NFS.  You would replace steps 3 & 4 with:
-
-	make CC=lynx-target-compiler...
