Installation (via NPM)
[sudo] npm install fuse -g
You need to install it globally, because it's nothing something that you can
require in your nodejs code. It's only a command line program.
On the command line
To run just once:
fuse.js -i path/to/main.js -o path/to/output.js
To watch a file for changes:
fuse.js -i path/to/main.js -o path/to/output.js -w
Fuse will automatically watch any referenced files for changes too, and recompile the output file upon any changes.
