-## Multipart form data parser
-
-### Features
-* No dependencies
-* Works with chunks of a data - no need to buffer the whole request
-* Almost no internal buffering. Buffer size doesn't exceed the size of the boundary (~60-70 bytes)
-
-Tested as part of [Cosmonaut](https://github.com/iafonov/cosmonaut) HTTP server.
-
-Implementation based on [node-formidable](https://github.com/felixge/node-formidable) by [Felix Geisendörfer](https://github.com/felixge).
-
-Inspired by [http-parser](https://github.com/joyent/http-parser) by [Ryan Dahl](https://github.com/ry).
-
-### Usage (C)
-This parser library works with several callbacks, which the user may set up at application initialization time.
-
-```c
-multipart_parser_settings callbacks;
-
-memset(&callbacks, 0, sizeof(multipart_parser_settings));
-
-callbacks.on_header_field = read_header_name;
-callbacks.on_header_value = read_header_value;
-```
-
-These functions must match the signatures defined in the multipart-parser header file.  For this simple example, we'll just use two of the available callbacks to print all headers the library finds in multipart messages.
-
-Returning a value other than 0 from the callbacks will abort message processing.
-
-```c
-int read_header_name(multipart_parser* p, const char *at, size_t length)
-{
-   printf("%.*s: ", length, at);
-   return 0;
-}
-
-int read_header_value(multipart_parser* p, const char *at, size_t length)
-{
-   printf("%.*s\n", length, at);
-   return 0;
-}
-```
-
-When a message arrives, callers must parse the multipart boundary from the **Content-Type** header (see the [RFC](http://tools.ietf.org/html/rfc2387#section-5.1) for more information and examples), and then execute the parser.
-
-```c
-multipart_parser* parser = multipart_parser_init(boundary, &callbacks);
-multipart_parser_execute(parser, body, length);
-multipart_parser_free(parser);
-```
-
-### Usage (C++)
-In C++, when the callbacks are static member functions it may be helpful to pass the instantiated multipart consumer along as context.  The following (abbreviated) class called `MultipartConsumer` shows how to pass `this` to callback functions in order to access non-static member data.
-
-```cpp
-class MultipartConsumer
-{
-public:
-    MultipartConsumer(const std::string& boundary)
-    {
-        memset(&m_callbacks, 0, sizeof(multipart_parser_settings));
-        m_callbacks.on_header_field = ReadHeaderName;
-        m_callbacks.on_header_value = ReadHeaderValue;
-
-        m_parser = multipart_parser_init(boundary.c_str(), &m_callbacks);
-        multipart_parser_set_data(m_parser, this);
-    }
-
-    ~MultipartConsumer()
-    {
-        multipart_parser_free(m_parser);
-    }
-
-    int CountHeaders(const std::string& body)
-    {
-        multipart_parser_execute(m_parser, body.c_str(), body.size());
-        return m_headers;
-    }
-
-private:
-    static int ReadHeaderName(multipart_parser* p, const char *at, size_t length)
-    {
-        MultipartConsumer* me = (MultipartConsumer*)multipart_parser_get_data(p);
-        me->m_headers++;
-    }
-
-    multipart_parser* m_parser;
-    multipart_parser_settings m_callbacks;
-    int m_headers;
-};
-```
