-      * **Important:** A source control manager URL cannot start with `http://` `https://`, `ftp://` or `file://`. For example, `https://github.com/keplerproject/wsapi.git` is incorrect, even though it works perfectly fine with `git clone`. The correct one is `git://github.com/keplerproject/wsapi.git`. Also note that only for GitHub URLs `git://` is being treated the same as `git+https://`. This is due to [GitHub's increased security](https://github.blog/security/application-security/improving-git-protocol-security-github/) and preserving backwards compatibility.

    * **source.md5** (string) - the MD5 sum for the source archive. Example: "9ca22fd9f9413b54802d3d40b38c4e5c"
    * **source.file** (string) - the filename of the source archive. Can be omitted if it can be inferred from the `source.url` field. Example: "luasocket-2.0.1.tar.gz"
    * **source.dir** (string) - the name of the directory created when the source archive is unpacked. Can be omitted if it can be inferred from the `source.file` field. Example: "luasocket-2.0.1"
