Compile the javascript: ~/asciiflow2$ ./compile.sh If you get a permissions error: ~/asciiflow2$ chmod a+x closure-compiler.jar Run a simple web server: ~/asciiflow2$python -m SimpleHTTPServer Goto: http://localhost:8000/index.html When developing, use the Google JS linter, gjslint. Adding new source files will require a change to compile.sh.
