3# System configuration variables:
4#
5# SYS_INCLUDE	"symlinks": symlinks to include directories are created.
6#		This may not work 100% properly for all headers.
7#
8#		"copies": directories are made, if necessary, and headers
9#		are installed into them.
10#
11# Variables:
12#
13# INCSDIR	Directory to install includes into (and/or make, and/or
14#		symlink, depending on what's going on).
15#
16# KDIR		Kernel directory to symlink to, if SYS_INCLUDE is symlinks.
17#		If unspecified, no action will be taken when making include
18#		for the directory if SYS_INCLUDE is symlinks.
19#
20# INCS		Headers to install, if SYS_INCLUDE is copies.
21#
22# DEPINCS	Headers to install which are built dynamically.
23#
24# SUBDIR	Subdirectories to enter
25#
26# SYMLINKS	Symlinks to make (unconditionally), a la bsd.links.mk.
27#		Note that the original bits will be 'rm -rf'd rather than
28#		just 'rm -f'd, to make the right thing happen with include
29#		directories.
