I've found myself converting font's at the beginning of most projects. I'll always convert one .ttf into one of .eot, .woff, or .svg. I decided this process should be automated:
$ gem install convert_font
convert_font convert -i /home/myproject/my_font_file.ttf -f eot,woff,svg
-i Is the absolute path to your font file.
-f Is a comma separated list of the file types you would like.
Your fonts will be dropped into your current working directory.
See the README for advanced usage.
(Disclaimer) Please only convert fonts you have the permission to do so with.
