Added, cheers!

One more thing, you should add a pkgver function so that the version number is adjusted automatically:

@gmes78 Thank you for that! Updated accordingly, and I'll update the README to reflect the name change.

Here's a patch to fix the build failure caused by using cargo install:

By the way, this package should have a -git suffix in its name, as it build from the latest git commit. The non -git packages are supposed to install versioned releases.
