This package is still in an experimental state.
A library to write Google Apps Script.
This library has been written on a per-need basis. As such it is missing lots
of useful functionality that I just hadn't needed yet. Until the API coverage
is nearing completeness I recommend to checkout the GIT repository during
development and to use this library with a path directive, adding the missing
functions when they are encountered.
Consider contributing your changes back to the original repository.
