# End component definition section

# This section defines tests for optional software.  These work off four
# types of variables:  WANT_GNOME, WITH_GNOME, HAVE_GNOME and USE_GNOME.
# The logic of this is that a port can WANT support for a package; a user
# specifies if they want ports compiled WITH certain features; this section
# tests if we HAVE these features; and the port is then free to USE them.

# The logic of this section is like this:
#
# .if defined(WANT_GNOME) && !defined(WITHOUT_GNOME)
#   .for foo in ALL_GNOME_COMPONENTS
#     .if defined(WITH_GNOME)
#       HAVE_GNOME += foo
#     .elif (foo installed)
#       HAVE_GNOME += foo
#     .else
#       Print option message
#     .endif
#   .endfor
# .endif
#
# Although it appears a little more convoluted in the tests.

# Ports can make use of this like so:
#
# WANT_GNOME=		yes
#
# .include <bsd.port.pre.mk>
#
# .if ${HAVE_GNOME:Mfoo}!=""
# ... Do some things ...
# USE_GNOME=		foo
# .else
# ... Do some other things ...
# .endif

# If the user has not defined GNOME_DESKTOP_VERSION, let's try to prevent
# users from shooting themselves in the foot.  We will try to make an 
# intelligent choice on the user's behalf.
