Font Custom is a tool that will generate custom icon webfonts from the comfort of the command line. It is very easy to use, all you have to do is create a directory for your svg and eps files. Then, on the command line, run: fontcustom watch /path/to/vectors
Font Custom will then create the font and CSS file. It will also continue to run and watch the folder for changes, so you don't have to manually re-run it each time you update the vector set.
