+
+Using Thrift with Javascript
+=====================
+
+Allows javascript client interfaces to Thrift services.
+This is geared for use in a web browser.
+
+This client can only speak the JSON Protocol and the only supported
+transport is AJAX.
+
+There is a test httpd service in the test dir that requires
+http://hc.apache.org under test dir
+
+Dependencies
+============
+A JavaScript enabled browser. Tested with:
+ *IE 6,7,8
+ *FF 2,3
+ *Safari 3 & 4
