## API
`extract(cb)` returns a transparent trhough stream (its output is the same as its input). Upon having seen the `` tag in the input, it calls `cb(err, meta)`, where meta has these propertues:
- name
- description
- author
- generator (coming from ``
- http (an object with http headers coming from `` tags
If there are meta tags with name or property attributes containing a colon (:), they are considered "namespaced meta tags" and occur in meta.namespaced. For example, `` shows up as `meta.namespaced.twitter.ceator`
## CLI
`html-extract-meta < in.html > out.json [--through]`
Reads html from stdin and outputs meta json to stdout. if `--through` is given, outputs meta json to stderr and outputs html to stdout.
