### WebSocket server/client implementation in Object Pascal
4+
5+
This project is based directly on pure Pascal source code.
6+
7+
Project contains implementation of clients and servers using WebSocket protocol RFC (http://tools.ietf.org/html/rfc6455)
8+
9+
This library is a remastered, rewritten and customized version of
10+
https://github.com/MFernstrom/Bauglir-WebSocket-2
11+
and
12+
https://github.com/Robert-112/Bauglir-WebSocket-2
13+
which originally are based on Bronislav Klucka source code as
14+
http://code.google.com/p/bauglir-websocket
15+
This library requirements Ararat Synapse (http://www.ararat.cz/synapse/) socket library to compile.
