html2latex
  Convert HTML document into LaTeX. Ruby script. incomplete.
  Usage:

  Why this script is here?
    To exploit code for makeref. :-)
makeref
  Read HTML document and number the anchors. Print numbered document
  into standard output and append reference index. Ruby script.
  Usage:
    makeref [-u] [-url base_url] [file]
    -url: Specify URL of the document. It is used to complete link
          in the document.
    -u: Append URL after each anchor, instead of reference number.
  Bugs
    If there are any error in HTML (unbalanced < , character entity
    without ; , etc.), output will be miserable.
htmldump
  Read HTML document from URL, number the anchors and format it,
  and output it on standard output.
  Usage
    htmldump [-u] [URL]
    -u: Append URL after each anchor, instead of reference number.
    If URL is omitted, $WWW_HOME is used instead.
  Bugs
    It assumes that the document on URL is HTML.
    As it uses makeref to number the anchor, it can't handle any document
    makeref can't handle.
