4-current post bison-removal and to a no-op otherwise. Note this
should only be used when the software in question uses a feature
in bison that is not in byacc -- otherwise it should be patched to
use byacc (or detect the absense of bison correctly). [bsd.port.mk]
(2) Do not assume all category names are lowercase. In particular,
remove package links by removing them one by one, instead of doing
a "rm [a-z]*/${PKGNAME}.tgz". [bsd.port.mk]
(3) Do not assume the category name doesn't include a path separator
(/). Make links accordingly. [bsd.port.mk,README.category,README.port]
(4) Do not assume all category makefiles are directly under
${PORTSDIR}. [bsd.port.mk,README.category]
(5) Add new "package-name" target which prints out the directory name
to be used in the parent README.html. [bsd.port.subdir.mk]
(2) through (5) are in preparation for going to multi-level
categories. They shouldn't make any difference yet, but are committed
first so people can start testing.
