NOTE: These examples will only work if the 'idc' compiler has been
installed.  To compile them without installing you will have to:

  - point the Makefiles at the uninstalled 'idc' by setting the
    variable IDC on the command line; 

  - tell 'idc' where to find its own compiled runtime libraries with
    -the B option; and

  - tell 'idc' where to find the compile-time st80 libraries with the
    -I option

like this:

	cd hw
	make IDC="../../../boot/idc -B../../../boot/ -I../../st80"
	LD_LIBRARY_PATH=$PWD/../../../boot ./hw

NOTE: Compilation can be long on slow hardware because many of the
examples import 'st80' causing the compiler to scan the source of the
entire Smalltalk-80 library.  (Most of them would probably work fine
importing nothing more than Object.)  In no particular order...

    replace 'switch()'-like statements.

interp

    A cheesey little example of a cheesier little interpreter.
    Demonstrates how closures in method dictionaries can share a
    single implementation but have different behaviour depending on
    the data stored in the closure.

libs1

    Example showing how to build and link against static libraries
    ('.a' archives).  Note that the linker will be forced to load all
    'Id' files found in the archive (regardless of whether they are
    used at runtime) and that the final program can be moved into (or
    run from) a different directory and it will still work (since all
    potentially-used libraries are linked statically into the
    executable).

libs2

    How to build and link against dynamic libraries.  Note that the
    final program can NOT be moved into (or run from) a different
    directory since the runtime will no longer be able to find the two
    libraries.  Either of the libraries can be modified without
    relinking the main program.

    How to build and link against a dynamic library constructed from
    multiple separately-compiled source files.
