Creating your first project in C2 is easy, just do:

~$ mkdir hello
~$ cd hello
~/hello$ <your favourite editor> hello.c2
~/hello$ <your favourite editor> recipe.txt
~/hello$ c2c

and use the following skeleton files:

hello.c2

module hello;

import stdio as io;

public func i32 main(i32 argc, char*[] argv) {
    io.printf("Hello C2!\n");
    return 0;
}

recipe.txt

executable hello
  $warnings no-unused
  $generate-c
  hello.c2
end

Calling tree will show the output:

.
├── hello.c2
├── output
│   └── hello
│       ├── build
│       │   ├── Makefile
│       │   ├── build.log
│       │   ├── hello.c
│       │   ├── hello.h
│       │   └── hello.o
│       └── hello
└── recipe.txt

As you can see, c2c will generate all required .c and .h files and the Makefile to build. Depending on the options in the recipe, c2c will generate a single .c/.h pair per module or per target.
