INFO="Watch online videos without flash using mplayer, quvi, youtube-dl etc.

This script is a valid bash script, greasemonkey (gm) script, and an html page.
- As a bash script, becomes a web server accepting the following request types:
  - http://*  -> Play a remote video extracted from URL.
  - file://*  -> Play a local video at the specified path.
  - mplayer:* -> Send command to mplayer running in slave mode.
- Server has a basic web interface to control mplayer, submit URLs, or download
  a js bookmarklet and/or a gm script.  Gm script pings the server with visited
  web pages (http only).  Js bookmarklet sends the current page when clicked on.

How to use it:
- On server, run this as a bash script (e.g. bash `basename $0`).
- On client (can be the same machine), go to http://$NOFLASH_SERVER:$NOFLASH_PORT
  and install the javascript bookmarklet and/or the greasemonkey script.
- With the gm script, videos from supported sites should start automatically as
  you browse.  If you prefer to use the js bookmarklet, click on it to initiate.
- Server binds to localhost only by default.  Change NOFLASH_SERVER to server's
  IP to be able to access and remote control it from other computers (clients).
- See http://www.cs.umn.edu/~oztekin/software/noflash for more information."
