A quick and dirty dust.js command line compiler (written in NodeJS, for use elsewhere)

dust_lib_server.js

// you need to take out this line for it to work with node 0.6+:

// comment out this line in the dust/lib/server.js file after "npm install dust":

require.paths.unshift(path.join(__dirname, '..'));

// otherwise, you'll get: 

/*
node test/server.js

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead.
