# the user/port can now set this options in the makefiles.
#
# WITH_NCURSES_BASE=yes	- Use the version in the base system.
# WITH_NCURSES_PORT=yes	- Use the port, even if base is up to date
#
# USE_NCURSES_RPATH=yes	- Pass RFLAGS options in CFLAGS,
#			  needed for ports who don't use LDFLAGS
#
# Overrideable defaults:
#
# NCURSES_SHLIBVER=	5
# NCURSES_PORT=		devel/ncurses
#
# The makefile sets this variables:
# NCURSESBASE		- "/usr" or ${LOCALBASE}
# NCURSESLIB		- path to the libs
# NCURSESINC		- path to the matching includes
# NCURSESRPATH		- rpath for dynamic linker
#
# MAKE_ENV		- extended with the variables above
# CONFIGURE_ENV		- extended with LDFLAGS
# BUILD_DEPENDS		- are added if needed
# RUN_DEPENDS		- are added if needed

#	if no preference was set, check for an installed base version
#	but give an installed port preference over it.
