It uses doxygen to generate the API documentation. For each subsystem a very small (about 20 lines with comments) subsystem specific Doxyfile has to be written (have a look at the README for more). All common doxygen options are specified in a separate file. The framework is configured to not only generate the HTML version, but also a PDF version (the paper size is hardcoded to DIN A4 currently and depending on the subsystem you have to increase some limits in the latex configuration of your system, the README tells more about this). It also allows cross-references between the subsystems (it generates doxygen tag files). Currently the docs are generated in OBJDIR, but this may change after coordination with doc@. The makefile is prepared to generate/move various parts of the generated docs to different destinations. TARGET_ARCH is respected and some env-vars are set for architecture specific handling of the source (the README tells more). Subsystems for which docs are generated: - cam - crypto - dev_pci - dev_sound - dev_usb - geom - i4b - kern - libkern - linux - net80211 - netgraph - netinet - netinet6 - netipsec - opencrypto - vm Requested by: gnn
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
