 The syntax for legacy meson (Version `0.29`) is a bit different.

 1. Manually create `build` directory and invoke meson as `meson . ./build`
 2. If you want to set options, this is done in one step.

-## Building the Debian Package
-
-To build a .deb file for installation on Debian platforms, perform the
-following steps:
-+ Run `sudo apt install devscripts` to install the `debuild` utility.
-+ Update the `debian/changelog` to reflect the changes in this release.
-+ If necessary, update the year of the copyright in `debian/copyright`.
-+ Clean any build artifacts: Run `make clean` and delete the `bin` directory,
-if it exists.
-+ Run `tar -xcvf ../urbit-x.y.z.orig.tar.gz .` from the top-level folder in
-the repo.  This command will create an archive in the directory above the
-current directory, which will be used in packaging.
-+ Run `debuild -us -uc`, also from the top-level folder in the repo. This
-creates a .deb file in the folder above the current directory.
-
-The resulting .deb file should now exist in the folder above the current
-directory. To test that the .deb file works properly, you can perform the
-following steps:
-+ Uninstall urbit: `sudo apt remove urbit`.
-+ Run `sudo dpkg -i ../urbit-x.y.z_amd64.deb` to install the new version.
-+ Boot up a ship using the `urbit` command.
