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 [http://bugs.gentoo.org/show_bug.cgi?id=278541 Gentoo package]:
   * Bump version number
   * `FEATURES=test emerge 0ad`
   * Upload to Bugzilla
 * On error goto beginning
 * Upload releases to server
 * Verify sha1sums on server
 * Update LatestRelease page (all links and checksums)
 * Announce release
