Original commit message from CVS: * new parser that uses flex and bison - doesn't do dynamic pipelines yet... * added GErrors to the gst_parse_launch[v] api * added --gst-mask-help command line option * fixed -o option for gst-launch * GstElement api change: - gst_element_get_pad - gst_element_get_request_pad, gst_element_get_static_pad - gst_element_get_compatible_pad - gst_element_get_compatible_static_pad, gst_element_get_compatible_request_pad - gst_element_[dis]connect -> gst_element_[dis]connect_pads - gst_element_[dis]connect_elements -> gst_element_[dis]connect * manual update * example, tool, and doc updates for the api changes - no more plugin docs in the core docs, plugins require a more extensive doc system
