/* 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.
