Simple macro for creating Command.

Please read the syntax description in the crate's documentation.

Please note that this macro is not whitespace-sensitive and the following will evaluate to four separate arguments (as opposed to one in command!):

cmd!(echo (foo)(bar)baz(qux)) // don't do it!

Examples

#[macro_use] extern crate command_macros;

fn main() {
    cmd!( echo ((2+2)) ).status().unwrap();
}
