+# tmhOAuth
+
+An OAuth 1.0A library written in PHP by @themattharris, specifically for use
+with the Twitter API.
+
+**Disclaimer**: This project is a work in progress and may contain bugs.
+
+## Goals
+
+- Support OAuth 1.0A
+- Use Authorisation headers instead of query string or POST parameters
+- Allow uploading of images
+- Provide enough information to assist with debugging
+
+## Dependancies
+
+The library has been tested with PHP 5.3+ and relies on CURL and hash_hmac. The
+vast majority of hosting providers include these libraries and run with PHP 5.1+.
+
+The code makes use of hash_hmac, which was introduced in PHP 5.1.2. If you version
+of PHP is lower than this you should ask your hosting provider for an update.
+
+## Usage
+
+This will be built out later but for the moment review the examples for ways
+the library can be used. Each example contains instructions on how to use it
+
+## Change History
+0.4 03 March 2011
+ Fixed handling of parameters when using DELETE. Thanks to yusuke for reporting
+ Fixed php_self to handle port numbers other than 80/443. Props: yusuke
+ Updated function pr to use pre only when not running in CLI mode
+ Add support for proxy servers. Props juanchorossi
+ Function request now returns the HTTP status code. Props: kronenthaler
+ Documentation fixes for xAuth. Props: 140dev
+ Some minor code formatting changes
+
+0.3 28 September 2010
+ Moved entities rendering into the library
+
+0.2 17 September 2010
+ Added support for the Streaming API
+
+0.14 17 September 2010
+ Fixed authorisation header for use with OAuth Echo
+
+0.13 17 September 2010
+ Added use_ssl configuration parameter
+ Fixed config array typo
+ Removed v from the config
+ Remove protocol from the host (configured by use_ssl)
+ Added include for easier debugging
+
+0.12 17 September 2010
+ Moved curl options to config
+ Added the ability for curl to follow redirects, default false
+
+0.11 17 September 2010
+ Fixed a bug in the GET requests
+
+0.1 26 August 2010
+ Initial beta version
+
+## Community
+
+License: Apache 2 (see included LICENSE file)
+
+Follow me on Twitter: <http://twitter.com/themattharris>
+Check out the Twitter Developer Resources: <http://dev.twitter.com>
+
+## To Do
+
+- Add good behavior logic to the Streaming API handler - i.e. on disconnect back off
+- Add demo of responsible rate limit handling
+- Async Curl support
+- Split Utilities functions out
