-# HOW TO UPDATE THE ZONEINFO DATA
-#
-# With the use of subversion, this is a little bit simpler than the CVS method.
-#
-# Import the new sources to the vendor branch:
-#
-# $ cd ~/svn/vendor/tzdata/dist
-# $ tar zxvf /usr/ports/distfile/tzdata2008X.tar.gz
-#   (check with "svn stat" and "svn diff" if it all makes sense)
-# $ svn commit	# Commit message: "Vendor import of tzdata2008X (+details)" 
-#
-# Tag it
-#
-# $ cd ~/svn/vendor/tzdata
-# $ svn cp svn+ssh://svn.freebsd.org/base/vendor/tzdata/dist \
-#	svn+ssh://svn.freebsd.org/base/vendor/tzdata/tzdata2008X
-# $ svn update	# Commit message: "Tag of tzdata2008X"
-#
-# Merge-from-vendor
-#
-# $ cd ~/svn/head/share/zoneinfo
-# $ svn update
-# $ svn merge -c X --accept=postpone \
-#	svn+ssh://svn.freebsd.org/base/vendor/tzdata/dist .
-# $ svn update	# Commit message: "MFV of tzdata2008X"
