#
# 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"
