The BSDBook Project is an effort at documenting the internals and the interface to the FreeBSD Kernel. This includes parts such as the File
Systems, VM Subsystem, Device Drivers, KLDs etc. Routines used
inside the kernel will be documented.
This project aims to define a common language for PIM module (addressbook, MUA, calendar, notes) interactions. Developers of PIM solutions or PIM components are invited to take part.
