Without looking, I'm going to guess that you created that library,
Joel.  That immediately assures me of its quality, but I found some of
the API a little unwieldy.

formats = { /\.txt$|\.html$/ => :text, /\.png$/ => :binary }
  # And should the programmer really have to specify these? Can't they
be baked in?

I don't get a sense of what that line is doing.

Seems to me that building yaml, json and marshal capabilities into the
library would be justified and worthwhile.

I'm starting work on a project involving a lot of file and directory
manipulation, so I'll check out fsdb enthusiastically.
