XMPP Smack Library Compilation

Hello,

I have some difficulties with implementing changes (see below) in Smack library and compiling the code for further use.

Rebind:
Create class Rebind extends Nonza
Smack/tcp -> XMPPTCPConnection -> PacketReader
Add rebind to PacketReader

I will need a detailed step-by-step walkthrough on how to implement any changes and compile the library.

I'd very much appreciate some help.

Thank you!
