# We can safely delete the ${TCL_PACKAGE_DIR}/darwinports1.0 dir as files in it are always overwritten and will now be installed onto
# ${TCL_PACKAGE_DIR}/macports1.0 with new names:
	[ ! -d ${TCL_PACKAGE_DIR}/darwinports1.0 ] || rm -rf ${TCL_PACKAGE_DIR}/darwinports1.0

# MacPorts base files in ${datadir} are also safely removed as new ones are always installed, and onto a their new location in this case too:
	[ ! -d ${datadir}/darwinports ] || rm -rf ${datadir}/darwinports

# Important directories inside ${localstatedir}/db/dports are moved to their new location, creating it first:
	mkdir -p ${localstatedir}/macports
	for dir in distfiles packages receipts software; do \
		[ ! -d ${localstatedir}/db/dports/$${dir} ] || mv -v ${localstatedir}/db/dports/$${dir} ${localstatedir}/macports ; \

	${localstatedir}/macports/sources/rsync.macports.org/release && mv -v \
	${localstatedir}/db/dports/sources/rsync.rsync.darwinports.org_dpupdate_dports ${localstatedir}/macports/sources/rsync.macports.org/release/ports ; }

# Old version file can be safely deleted, as it was already used to start this upgrade and a new one will be installed into the new location:
	[ ! -f ${sysconfdir}/ports/dp_version ] || rm -vf ${sysconfdir}/ports/dp_version

# The main configuration file is first renamed to macports.conf while still in its old dir:
	[ ! -f ${sysconfdir}/ports/ports.conf ] || mv -v ${sysconfdir}/ports/ports.conf ${sysconfdir}/ports/macports.conf

# Following that, the dir itself is renamed to its new name:
	[ ! -d ${sysconfdir}/ports ] || mv -v ${sysconfdir}/ports ${sysconfdir}/macports

# Open up receipts and upgrade any paths in them containing old conventions to the new namespace:
	for receipt in ${localstatedir}/macports/receipts/*/*/receipt.bz2 ; do \
		cp -v $${receipt} $${receipt}.old && { \
			$(BZIP2) -q -dc $${receipt} | sed 's/db\/dports/macports/g' | $(BZIP2) -q -zf > $${receipt}.new ; \
		} && mv -v $${receipt}.new $${receipt} ; \

		mv -v ${sysconfdir}/macports/sources.conf.tmp ${sysconfdir}/macports/sources.conf

# New default values for the base and ports trees are inserted into the macports.conf and sources.conf configuration files:

		mv -v ${sysconfdir}/macports/sources.conf.tmp ${sysconfdir}/macports/sources.conf

# Stray quotes are removed from the value of the rsync_options key in old conf files:
	sed '/^rsync_options/s/"\(.*\)"/\1/' ${sysconfdir}/macports/macports.conf > ${sysconfdir}/macports/macports.conf.tmp && \
		mv -v ${sysconfdir}/macports/macports.conf.tmp ${sysconfdir}/macports/macports.conf


#something more?

# References to the old ports.conf(5) man page are updated to the new macports.conf(5) page:
	sed 's/ports.conf(5)/macports.conf(5)/g' ${sysconfdir}/macports/macports.conf > ${sysconfdir}/macports/macports.conf.tmp && \
		mv -v ${sysconfdir}/macports/macports.conf.tmp ${sysconfdir}/macports/macports.conf

# Finally, move remaining instances of any form of our new name (which by this time should only remain in comments, if at all) to our new name:
	sed 's/[Dd]\(arwin\)\{0,1\}[Pp]\(orts\)\{0,1\}/MacPorts/g' ${sysconfdir}/macports/macports.conf > ${sysconfdir}/macports/macports.conf.tmp && \
