FYI: Distfile survey back up

[Bill Fenner]

The distfile survey, http://people.freebsd.org/~fenner/portsurvey/
is back up and running after an.. um.. 'hiatus'.  It's still got one
major limitation, which is that it doesn't know that an empty reply
to "ls" is equivalent to a "file doesn't exist" - I'll work on this,
and then hopefully I'll work on the output format so that it's less
incomprehensible.
