Possible targets for ad-hoc ports operations?

[Brad Ely <elyb_(_at_)_ioplasm_(_dot_)_net>]

The way bsd.port.mk is written makes it fairly easy to implement
the following for-{all,build,run}-depends target(s) to do ad-hoc
operations with the ports infrastructure.  Just pass in a statement
to be executed within the context of the makefile target.

For example:

(cd to port dir)
make for-all-depends='make fetch || true'
make for-all-depends='make checksum'
make for-all-depends='make clean=packages'

make for-all-depends='make show="PKGNAME MULTI_PACKAGES FLAVORS"'
make for-all-depends='make show="FULLPKGNAME MAINTAINER"' | xargs -L2
make for-all-depends='make print-package-signature'

find `make for-all-depends=pwd` ! -path '*CVS*' -type f -mtime -10
make for-all-depends='printf "%s\t%s\t%s\n" $$dir $$multi $$flavor'

Any good?
Brad Ely
