Tiny Compiler/Interpreter Installation
	    Under Windows using Cygwin
        (contributed by Jeremy Tartaglia)

Installation requirements:

	1)  A Win32 Operating System (Windows 95/98/NT/ME/2000/XP are all
            currently supported by Cygwin).
	2)  Cygwin with GNU C, Make, Flex, and Bison packages installed. 
            (See Cygwin Installation Procedures.  Each is underneath the dev node.)
	3)  A text editor.

Cygwin Installation Procedures:

	1)  Download the setup.exe program from Cygwin's homepage
            (currently at http://www.cygwin.com).
	2)  Execute the program, and select directories for installation, packages,
            temporary files, and other such mundane details.  (The Cygwin directory
            you chose will be referred to as C:\Cygwin for the remainder of this
            installation procedure.)
	3)  When you get to the package installation step, you should see a list
            of names with circular arrows next to them.  They should all be set to
            default.  You need to find the Development package (sometimes labeled Dev,
            sometimes Devel depending on the setup program), and either select the
            whole development package for installation (by click the arrow until
            it reads "Install") or select only the necessary packages gcc, flex,
            and bison.
	4)  Finish the install.  Depending on the packages you chose to install,
            this could take a while.

Tiny Compiler/Interpreter Installation:

	1)  Download the Tiny Compiler/Interpreter.
	2)  If necessary, download an extraction program capable of extracting
            tar.gz (Tape Archive and GZiped) files.  A fairly complete, free
            extractor exists at http://www.7-zip.org.
	3)  Extract the contents of the file into C:\Cygwin\usr.  This must be done
            since, in Cygwin, it is not possible to easily access anything outside
            the Cygwin directory.
	4)  Go into C:\Cygwin\usr\tws\pgen, and open Makefile in a text editor.
	5)  Count down to line 28, and you will see "yacc -dv Parser.y".  Change
            this to read "bison -dv Parser.y" instead.
	6)  Immediately after the "bison -dv Parser.y" line, insert these 
            lines as part of the same rule:
            "cp Parser.tab.c y.tab.c"
            "cp Parser.tab.h y.tab.h"
	7)  Count down to line 34, and you will see "lex Tokenizer.l". Change this
            to read "flex Tokenizer.l" instead.
	8)  Save the file, and run Cygwin.
	9)  Type the following:  cd /usr/tws ; make all

After that, the Tiny Compiler/Interpreter should be working correctly.
