Brief approximation:
 * Check that SVN compiles and runs on Linux
 * Check that SVN compiles and runs on Linux with `--without-pch`
 * Check that SVN compiles and runs on Windows
 * Check that SVN compiles and runs on OS X
 * Run Windows autobuilder
 * Update public trunk checkout
 * Ensure it is clean (`svn st --no-ignore`)
 * Run `source/tools/dist/build.sh`
 * Test on Windows:
   * Delete `%appdata%\0ad\cache`
   * Extract release
   * Run `pyrogenesis.exe`, check everything seems to work
   * Run `Atlas.bat`, check everything seems to work
   * Delete `%appdata%\0ad\cache`
   * Build Debug version, check everything seems to work
   * Run `test` project
 * Test on Linux:
   * Delete `~/.cache/0ad`
   * Extract release
   * Build, `test_dbg`, run game, run editor
   * `CONFIG=Release` build, `test`, run game, run editor
 * Test on OS X:
   * Update !MacPorts
   * Same as Linux (but editor won't work)
 * Update OBS packages [https://build.opensuse.org/package/show?package=0ad&project=games 0ad], [https://build.opensuse.org/package/show?package=0ad-data&project=games 0ad-data]:

   * Replace `.tar.gz` with new version
 * Update [https://launchpad.net/~wfg/+archive/0ad PPA packages]:
   * Find an Ubuntu machine.
   * Copy `source/tools/dist/ubuntu/` into a place for packaging
   * Update `changelog` files
   * Update `build.sh` version number
   * Run `build.sh`. (Optionally disable the `debuild -b` lines because they're not needed, we only require the source packages.)
   * `dput ppa:wfg/0ad <source.changes>`
 * Update [http://bugs.gentoo.org/show_bug.cgi?id=278541 Gentoo package]:
   * Bump version number
