+In this directory, there are the following files:
+
+    Makefile  - Example Makefile file
+    README    - the file you are reading.
+    hello.adb - simple hello world file
+    init.c    - RTEMS initialization thread which invokes the Ada main
+
+The following make stanza are included:
+
+    all   - This stanza builds the executable hello.
+
+    run   - This invokes the SPARC Instruction Simulator (SIS) on hello.
+
+    gdb   - This invokes gdb with the integrated SPARC Instruction
+            Simulator (SIS) on hello.
+
+    clean - This stanza removes all generated files.
+
+The tool directory must be in your path for this to work.

+SAMPLE SESSION WITH SIS
+=======================
+
+The following is a sample session with sis:
+
+    $ gmake run
+    /home/joel/gnat-3.10b/sparc-rtems//bin/sis hello
+
+     SIS - SPARC intruction simulator 2.7.4,  copyright Jiri Gaisler 1995
+     Bug-reports to jgais@wd.estec.esa.nl
+    
+    loading hello:
+    section .text at 0x02000000 (159152 bytes)
+    section .data at 0x02026db0 (4384 bytes)
+    section .bss at 0x02027ed0 (30948 bytes)(not loaded)
+    serial port A on stdin/stdout
+    sis> go
+    resuming at 0x02000000
+    Hello World
+    IU in error mode (257)
+       712144  02000800  91d02000  ta  0
+    sis> quit
+
+Note that the user typed "go" to start the executable and "quit" to
+exit the simulator.  The normal exit message is "IU in error mode (257)"
+because the program exits by generating an unhandled trap.
+
+ 
+SAMPLE SESSION WITH GDB
+=======================
+
+The following is a sample session with sis:
+
+    $ gmake gdb
+    /home/joel/gnat-3.10b/sparc-rtems//bin/sis-gdb hello
+    GNU gdb 4.16.1a
+    Copyright 1996 Free Software Foundation, Inc.

+    welcome to change it and/or distribute copies of it under certain conditions.

+    This GDB was configured as "--host=i486-linux --target=sparc-erc32-aout"...
+    
+     SIS - SPARC instruction simulator 2.7.4
+     Bug-reports to Jiri Gaisler ESA/ESTEC (jgais@wd.estec.esa.nl)
+    serial port A on stdin/stdout
+    Connected to the simulator.
+    loading /usr1/rtems/work/tools_ada/example/hello:
+    section .text at 0x02000000 (159152 bytes)
+    section .data at 0x02026db0 (4384 bytes)
+    section .bss at 0x02027ed0 (30948 bytes)(not loaded)
+    (gdb) run
+    Starting program: /usr1/rtems/work/tools_ada/example/hello 
+    Hello World
+
+    Program exited normally.
+    (gdb) quit
+
+Note that the user typed "run" to start the executable and "quit" to
+exit the debugger.  Other gdb commands function the same as when gdb
+is used natively.
+
+The program "sis-gdb" is a script which always invokes a command file
+to initialize the simulator and load the executable into the simulator's
+memory.
