OSSGadget

OSS Download provides a shortcut to download a package. This can be useful in a few different scenarios:

You are operating across multiple package management ecosystems.
You don't have (or want) native tools installed, like NPM or Python/PIP.
You need to download many packages, and therefore cannot use a web-browser.

OSS Download takes a Package URL and calls a module specific to the package manager. For example, if an NPM package is requested, code will run to query the NPM registry for the project, searching for the correct binary. Once found, it downloads it, and by default, extracts it into a new directory.

Note that for GitHub projects, the git ls-remote command is currently needed to enumerate tags, which means that you need to have git installed and available on the path.
