DESCRIPTION:
	This program is to solve the problem with CFExecute being unable to launch
	HTMLDoc in certain situations due to process memory usage limitations on the Jrun
	implementation of the exec() system call.
	

SRC:
	Contains the C source code for the program
	
BIN:
	Contains the precompiled Win32 exe file
	

Compile:
	Contains a ZIP of the Digital Mars C/C++ Compiler for Win32, and compilation
	instructions
	

PROGRAM DOCUMENTATION:
	The comments in the C file explain line by line what is going on.
	Basically, the program takes in the query string, which is passed by IIS
	to the CGI executable in the environment string of the program's memory space.
	This is standard for all CGI systems.
	
	The program obtains a long string of the environment by calling the getenv()
	function in the stdlib.h file.
	
	We then URL-Decode the string by iterating over its length and subsituting any
	instance of %## with the decimal equivalent of the hex code 0x00## and then
	converting that decimal to its ASCII character equivalent.
	
	We then split the query string to find the contentPath and fileName, which 
	must be specified in this order in the query string for the program to work
	correctly.
	
	It makes note of the locations of the & and both = signs within the string
	and then does some char pointer math to determine where the substrings
	need to start and end.  These then get copies of the data.
	
	A command string cmd is then built with all the arguments for htmldoc, and this
	is passed to the operating system via the system() call definedi n stdlib.h
	
	The OS then spawns a cmd.exe shell, and runs the command string.  When it terminates,
	generatePDF.exe gets control back, frees all dynamically allocated memory and terminates
	returning error code 0 (success) to the parent process (IIS).
