Please note that the content of this file is strictly advisory.
No locks listed here are valid. The only strict review requirements
are granted by core. These are documented in head/LOCKS and enforced
by svnadmin/conf/approvers.
The source tree is a community effort. However, some folks go to the
trouble of looking after particular areas of the tree. In return for
their active caretaking of the code it is polite to coordinate changes
with them. This is a list of people who have expressed an interest in
part of the code or listed their active caretaking role so that other
committers can easily find somebody who is familiar with it. The notes
should specify if there is a 3rd party source tree involved or other
things that should be kept in mind.
However, this is not a 'big stick', it is an offer to help and a source
of guidance. It does not override the communal nature of the tree.
It is not a registry of 'turf' or private property.
***
This list is prone to becoming stale quickly. The best way to find the recent
maintainer of a sub-system is to check recent logs for that directory or
sub-system.
***
***
Maintainers are encouraged to visit:
https://reviews.freebsd.org/herald
and configure notifications for parts of the tree which they maintain.
Notifications can automatically be sent when someone proposes a revision or
makes a commit to the specified subtree.

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. See build(7)
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.
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. See build(7), config(8),
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
for more information.
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 kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
