# this substitutes USE_OPENSSL=yes
# just include this makefile after bsd.ports.pre.mk
#
# the user/port can now set this options in the makefiles.
#
# USE_OPENSSL_BASE=yes	- Use the version in the base system.
# USE_OPENSSL_PORT=yes	- Use the port, even if base if up to date
# USE_OPENSSL_BETA=yes	- Use a snapshot of recent openssl
#
# The makefile sets this variables:
# OPENSSLBASE		- "/usr" or ${LOCALBASE}
# OPENSSLDIR		- path to openssl
# OPENSSLLIB		- path to the libs
# OPENSSLINC		- path to the matching includes
#
# MAKE_ENV		- extended with the variables above
# LIB_DEPENDS		- are added if needed

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