I seek a tool that can be run on the command line like so:

tablescrape 'http://someURL.foo.com' [n]

If n is not specified and there's more than one HTML table on the page, it should summarize them (header row, total number of rows) in a numbered list. If n is specified or if there's only one table, it should parse the table and spit it to stdout as CSV or TSV.

Potential additional features:

• To be really fancy you could parse a table within a table, but for my purposes -- fetching data from wikipedia pages and the like -- that's overkill. The Perl module HTML::TableExtract can do this and may be good place to start for writing the tool I have in mind.
• An option to asciify any unicode.
• An option to apply an arbitrary regex substitution for fixing weirdnesses in the parsed table.
