[commandline] trplayer kludge, but it works (fwd)

[Michael Whapples]

Why not just use something like mplayer? Much simpler as it tends to be 
packaged into distributions and supports many more formats. OK, mplayer 
I found needed the actual stream URL extracting from the .ram file (in 
the case of the BBC it just needed the content which is the stream URL, 
use a command like
mplayer $(cat filename.ram)
). Mplayer is just one example, there are others like xine.

Another alternative, if you want to make some work for yourself would be 
create a command line player based on something like gstreamer... Well 
for simple use you could even use some of the CLI tools included with 
gstreamer.

I really would leave trplayer alone.
