The manual pages are generated downstream in Debian and thus has to be updated with each release.

The debian/tsc.1 manpage is generated after updating typescript to the new version and installing
the corresponding built deb with the following command:

    help2man --name tsc --section 1 --output debian/tsc.1 --no-info --no-discard-stderr tsc

After that it takes some manual tweaks to make it somewhat palatable.

The tsserver.1 manpage is created from https://github.com/microsoft/TypeScript-wiki/blob/main/Standalone-Server-(tsserver).md
using `markdown2man`.
