Title: Python cmd line MPG player
Last Modified: 05.25.2008
This mpg player is based on curses, threading and pygst1. It uses gst to play the music. Threads, and curses for controls. I uses it to ssh in to a computer and play music. If your terminal doesn't support colors you have to disable the colors. Curses will complain.

Of course I haven't commented it. Notice the 'threads_init()'. Very nescessary, GTK has it's own threading and if you don't do that the other threads won't work very well.
The next phase of development, will be to add more command line options, like playlist files, random and repeat. And the mpg tags should be read to display relevant information....song title, artist, file information.
