hindent 1.1.2-8 (sparc binary) in ubuntu lucid

 This utility reformats HTML code to be properly indented/nested
 for improved readability. You can indent the existing lines as-is,
 or totally reformat the code to have one tag per line. Hindent is
 useful in deciphering software-generated HTML code when it's all just
 one huge line, or help you find that last missing end-tag, or
 deal with code victimized by creeping featurism.
 Written in Perl for Unix. Understands all HTML 3.2 nestable tags.
