/* CURL Extension Emulation Library (Console Binary)
 * Copyright 2004-2007, Steve Blinch
 * http://code.blitzaffe.com
 * ============================================================================
 *
 * DESCRIPTION
 *
 * Provides a pure-PHP implementation of the PHP CURL extension, for use on
 * systems which do not already have the CURL extension installed.  It emulates
 * all of the curl_* functions normally provided by the CURL extension itself
 * by wrapping the CURL console binary.
 *
 * This library will automatically detect whether or not the "real" CURL
 * extension is installed, and if so, it will not interfere.  Thus, it can be
 * used to ensure that, one way or another, the CURL functions are available
 * for use.
 *
 * This library is actually a wrapper for the CURL console application (usually
 * found in /usr/bin/curl), so you must have the CURL binary installed in order
 * to use this script.
 *
 *
 * USAGE
 *
 * Please see the PHP documentation under the "CURL, Client URL Library 
 * Functions" section for information about using this library.  Almost all of
 * the documentation and examples in the PHP manual should work with this
 * library.
