Xapian is split into several modules, which are held in sub-directories of the directory containing this file. The core code and documentation is in the xapian-core module.

If you're new to hacking on Xapian, you should probably start by reading the Xapian developer guide:

If you're new to Xapian entirely, you should probably read our user guide, and then look for further information on our website at https://xapian.org/

Experimental: we have support for building an Ubuntu VM using Vagrant and VirtualBox. The command vagrant up will start the process, although it can currently take a long time to download and install all the relevant packages. See "Using a Vagrant-driven Ubuntu virtual machine" in xapian-core/HACKING for details.
