I have tried to enhance the README file of this repo. Please have a loot at it. I suggest to rename the file to README.md & copy paste the following contents if you like the styling. Thanks.

### This program will generate a waveform at audio ranges (0-20,000Hz). You can change the frequency, volume/amplitude, and waveform type.

#### This program requires:
- [Python2](http://www.python.org/download)
- [Gstreamer](http://www.gstreamer.net/download)
- [gst-python](http://www.gstreamer.net/modules/gst-python.html)
- [urwid](http://excess.org/urwid)

#### Example usage:

*signalgen -f 200 -v 0.5 -w triangle -V*

Help Message:

#### Usage: signalgen -[options]
- Values for wave must be one of: sine, square, saw, triangle, silence, white-noise, pink-noise, sine-table, ticks, gaussian-noise.
- You can adjust the waveform properties at runtime by using the following keys such as up/down=volume, left/right=frequency, page up/page down=waveform.

#### Options:
* -h, --help show this help message and exit
* -f FREQ, --freq=FREQ frequency of signal from 0-20000, default 440
* -v VOL, --volume=VOL volume of signal from 0-1, default 0.8
* -w WAVE, --wave=WAVE oscillator waveform name, default 'sine'
* -c, --stdout outputs waveforms to stdout, default off
* -V, --visualize enable an X oscilloscope window, default off
* -a, --audio enable audio output, default on
* -q, --quiet don't print to stdout or stderr, default off

#### Installing:

Run 'python setup.py install' as root.

#### Bugs/Todo:

When using the --visualize option, closing the window causes the audio to stop playing but the program does not exit
automatically. Either the program should exit or the audio should continue to play until the program is exited normally.
