How to create the testABI

The example of the README.md is fine enough and fully understandable if one knows the solidity code. Still a formal documentation could help (for example I do not understand anonymous events).

But the translation from the solidity code to the Javascript definition of the function types can clearly be done automatically. Surely a script can be written. Has someone written such a script and would be interested in one?

Thank you very much for writing this.
EDIT: Found the solution. It is `solc Filename.sol --abi`. Should be part of the readme.
