"""pythonium

Usage: pythonium [-h][-d][-r][-V] [FILE ...] [-o FILE]|[-g]

Options:

-h --help show this

-v --version show version

-V --veloce use veloce mode, generated code is faster but least compliant

-o --output FILE specify output file [default: stdout]

-d --deep generate file dependencies. If --output is not provided, it will generate for each source file a coresponding .js file.

-r --requirejs generate requirejs compatible module

-g --generate generate pythonium runtime (exclusive option)

The default mode, without -V or --veloce option is *experimental*.

If you generate code without -V or --veloce you will need to use the library generated with -g or --generate option to run the code.
