The option should be included in the man pages for build:

https://www.freebsd.org/cgi/man.cgi?query=build&sektion=7&apropos=0&manpath=FreeBSD+10.2-RELEASE

"The default components included in the build are controlled by the file
/etc/src.conf in the source tree. To override the default file, include the
SRCCONF option in the make steps, pointing to a custom src.conf file. For
more information see src.conf."

Since I'm complaining, the src.conf file doesn't actually describe what
it's purpose is. It says it contains settings, but not what those settings
do. The reader is not informed of it's true purpose until they start
reading the list of  variables. There seems to be only one purpose to those
settings: to control the components included in a build. So:

 The *src.conf* file contains	settings that will apply to every build
     involving the FreeBSD source tree;	see build(7)
<https://www.freebsd.org/cgi/man.cgi?query=build&sektion=7&apropos=0&manpath=FreeBSD+10.2-RELEASE>.

becomes

 The *src.conf* file contains	variables that control what components
will apply to all builds
     involving the FreeBSD source tree;	see build(7)
<https://www.freebsd.org/cgi/man.cgi?query=build&sektion=7&apropos=0&manpath=FreeBSD+10.2-RELEASE>.


Thanks!
