      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.
