# 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
#
# INCSYMLINKS   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.
