# Variables:
#
# INCSDIR	Directory to install includes into (and/or make, and/or
#		symlink, depending on what's going on).
#
# INCS		Headers to install.
#
# DEPINCS	Headers to install which are built dynamically.
#
# SUBDIR	Subdirectories to enter
#
# SYMLINKS	Symlinks to make (unconditionally), a la bsd.links.mk.
#		Note that the original bits will be 'rm -rf'd rather than
#		just 'rm -f'd, to make the right thing happen with include
#		directories.
