Run focused scripts when files change.
An example configuration for a webpack based project:
#!/usr/bin/env node
var conservator = require('conservator');
conservator.service('./scripts/start:webpack', [
'*.webpack.config.*',
]);
conservator.task('./scripts/test:style', [
'{src,test}/**/*.{js,jsx}',
'*.js',
]);
conservator.task('./scripts/test:unit', [
'test/unit/**/*.js',
{'src/(**/*).{js,jsx}': 'test/unit/$1.js'},
]);
conservator.start();
