There are scripts to simplify the rendering process; to run them (and edit icons) you will need:
- inkscape
- ruby
For symbolic icons, these sources are "plates" that are split into the individual icons using the render-symbolic.rb script.
To render the symbolic icons from their respective source SVG files, run the following from the main source folder:
./render-symbolic.rb
This script will look in the source directory (../src/symbolic/*) and render the respective icons (provided there are changes).
