monado/debian

This package is based on the version of Monado in Debian
(https://salsa.debian.org/xr-team/monado), but is slightly adapted for use
directly within the "upstream" source tree.

There is useful stuff, more directed at package maintenance for distro
submission, in the Debian copy of this file:
<https://salsa.debian.org/xr-team/monado/-/blob/debian/sid/debian/README.source>

To build a package for local use:

- Checkout the branch you want to build (assuming `main` here) and make sure
  your tree is clean (`git reset --hard` will be used later!) A fresh clone or
  one kept clean just for package building is probably a good idea.
- Do a `git merge --no-commit debian/sid` (or `debian/buster-backports`, or
  `ubuntu/focal`, or...)
- `debian/extra/prepare-commit-package.sh main` to make the orig.tar.gz file
  and add the `debian/changelog` entry. (Add an additional command line argument
  with the debian revision if you want to customize it. The default is usually
  good.)
- `debuild -uc -us` to build an unsigned source and binary package on your
  machine. Or, however else you want to build. (e.g. `debuild -S` for a signed
  source-only package to upload to a PPA, etc)
- `git reset --hard` to undo the merging-in changes when you're done.
