# This file includes the mk.conf file, which contains the user settings.

# Packages should include this file before any of the .if directives, as
# well as before modifying variables like CFLAGS, LDFLAGS, and so on.
# Otherwise the behavior may be unexpected.
#
# When mk.conf is included by this file, the following variables are
# defined:
#
# ACCEPTABLE_LICENSES
#	This variable is set to the list of Open Source licenses. See
#	mk/license.mk for details.
#
# MACHINE_PLATFORM
#	The platform for which the packages are built. It has the form
#	${OPSYS}-${OS_VERSION}-${MACHINE_ARCH}.
#
# NATIVE_MACHINE_PLATFORM
#	The platform on which the packages are built. This is usually
#	the same as ${MACHINE_PLATFORM}, but can be different when
#	cross-building packages.
#
# PKGPATH
#	The path of the package, relative to the pkgsrc top-level
#	directory. Typical values look like editors/emacs or
#	misc/openoffice-bin.
