/**
 * Firstly, run `make psalm` to fetch the latest Psalm schema.
 *
 * Next, this script will parse through the schema file to get a list of the
 * "Issue Types" currently supported by Psalm. It will generate a new "template"
 * file that is used for the `@@VENDOR@@` token in `psalm.xml`.
 *
 * This is to work around a bug where `vendor` is not ignored correctly despite
 * a correct top-level definition.
 *
 * This hack is hopefully temporary.
