Now try to use those variables everywhere around DIST* and PATCH*
definitions as far as possible, for ease of the future updates and the
neatness.
Okay, 60% of `japanese' ports have been done. :)
bsd.port.mk that will be committed soon, this will disable automatic

built from separate scripts).
These are no-ops for ordinary users (i.e., when PACKAGE_BUILDING is
not defined).
