[HEADS UP] Planned deprecation of portsnap

[Tatsuki Makino]

By the way, there was a REFUSE directive in /etc/portsnap.conf, wasn't
there?
Isn't this a db space saver?

Or, rename the current fetch command to fetch-all.
Then the fetch command will be modified to download only where it is
needed based on the dependency graph.

portsnap fetch # <- download Mk/*, INDEX-1? and result of pkg info -oqa
portsnap extract # install it to /usr/ports
make -C /usr/ports/ search "name=git-[0-9]" # find a git. -> Path:
/usr/ports/devel/git
portsnap fetch devel/git # download the git-related stuff. ftp/curl,
lang/p5-Error, textproc/rubygem-asciidoctor, ...
security/p5-Authen-SASL, security/p5-IO-Socket-SSL
portsnap extract # Add a git-related tree.
