+	help
+	  This is a parser for HTTP messages written in C. It
+	  parses both requests and responses. The parser is
+	  designed to be used in performance HTTP applications.
+	  It does not make any syscalls nor allocations, it does
+	  not buffer data, it can be interrupted at anytime.
+	  Depending on your architecture, it only requires about
+	  40 bytes of data per message stream (in a web server
+	  that is per connection).
