Usage:
===============
Install the appropriate plugin for your preferred browser:

Firefox:
 Open the firefox_extension/rescuetime_exporter.xpi file in Firefox, and follow the instructions within Firefox to install it.

Epiphany:
 Run install.sh within the epiphany_extension directory. You may need to enable Epiphany extensions (in Ubuntu, run "sudo apt-get install epiphany-extensions").

Run "python setup.py build" then "sudo python setup.py install" to use setuptools to install the program. It will install a script into /usr/bin/rescuetime_linux_uploader that allows you to run the executable from the command line. It will also install the gnome panel applet.

To run from the command line:
 Run "rescuetime_linux_uploader" and follow the instructions to enter your username and password. These will be stored in $HOME/.rescuetime/preferences, should you need to change them.

To add to your gnome panel:
 Right click on your gnome panel, click "Add to Panel..", and select "RescueTime" from the "Utility" section. Fill out your username and password, if necessary.
jess@home:~/Desktop/rescuetime-linux-uploader-84$ python setup.py build

A simple solution?
