Generate the version automatically.
keep them in step with the npm package version
which is also the github release tag/version.
Which is "semver"
there's currently no straigtforward way to
compile time send variables into a spec.
So we generate a variables.tsp file from a "template"
The template is
`printf 'alias Version = \"%s\";\n' $npm_package_version > variables.tsp``
