/*
 * Project name: C4P eBook Wishlist Parser
 * Author: Isaac Good
 * Summary: TF of C4P wanted some HTML parsed with select bits stuck in a seperate text file.
 * This app reads a HTML file (file name given as the parameter), looks for a thread ("<a href=\"showthread.php?t=") and checks its not deleted,
 * and appends the thread title to out.txt
 * 
 * Project start:
 * July 9, ~12:00 am
 * Project end:
 * Jun 9, 3:15 am
 * 
 * This is under the MIT license like the rest of my software. See http://www.ecf.utoronto.ca/~goodi/html/software.html for the license.
