## Web UI Installation
 1. Extract tarball contents to somewhere under your web root
 2. Rename ``sample.config.inc.php`` to ``config.inc.php``, after optionally changing values in it
 3. Visit page in web browser
 4. Pass URL to your friends to show off


### URL arguments

- ``?out=json`` - JSON output
- ``?out=jsonp&callback=functionName`` - JSON output with a function callback. (Look here: http://www.json-p.org/ )
- ``?out=php_array`` - PHP serialized associative array
- ``?out=html`` - Usual lightweight HTML (default)

### Extensions
 - See a list of php files in src/Linfo/Extensions/
 - Open them and look at the comment at the top of the file for usage


## Troubleshooting:

Set ``$settings['show_errors'] = true;`` in ``config.inc.php`` to yield useful error messages.


## TODO:
 - Support for other Unix operating systems (Hurd, IRIX, AIX, HP UX, etc)
 - Support for strange operating systems: Haiku/BeOS
 - More superfluous features/extensions
 - Make ncurses mode rival htop (half kidding)
