Thanks for reporting this! Should be fixed in 485f92c.

One thing I have not yet figured out how to do is to import the JS output from compiling the client-side component (in https://github.com/the-gamma/thegamma-script) into this repo. On a local machine, I do that via symlink, but that's quite hacky solution (I added the build output here in 8d193bd so that things run).

Is there some standard JavaScript eco-system way of doing this? (In longer term, I'll package thegamma-script on NPM, but for development, I want to keep updating it pretty much every minute or two :-)). If you have any hints on doing, that, I'd welcome any advice!

(I'll write some Readme on building thegamma-script in a few days!)

I try to avoid the standard Javascript ecosystem as much as possible, but the standard way of depending on a module while developing it is npm link

Thanks! I will only have time to play with The Gamma during weekends, so no rush.
