+# RequestCore
+
+RequestCore is a lightweight cURL-based HTTP request/response class that leverages MultiCurl for parallel requests.
+
+### PEAR HTTP_Request?
+
+RequestCore was written as a replacement for [PEAR HTTP_Request](http://pear.php.net/http_request/). While PEAR HTTP_Request is full-featured and heavy, RequestCore features only the essentials and is very lightweight. It also leverages the batch request support in cURL's `curl_multi_exec()` to enable multi-threaded requests that fire in parallel.
+
+### Reference and Download
+
+You can find the class reference at <http://skyzyx.github.com/requestcore/>. You can get the code from <http://github.com/skyzyx/requestcore>.
