Samba codebase organization overview

Broadly speaking, the Samba source-code tree can be organized into the following major groups:

• Top-level libraries, which contains common code shared amongst the Samba processes.
• Source3, which is code primarily used by the file server and domain member.
• Source4, which is code primarily used by the Active Directory Domain Controller.
• Infrastructure components, which provide the build and test framework for Samba.
• Autogenerated code, which is used for parsing DCE/RPC packets as well as other regularly structured buffers.
