Commands:
  build - Builds the project belonging to the current diretory
  new - Launches the project creation wizard
  addpackage <package> - Adds a package to the project. Check CMakeLists.txt's top for a list of the ones currently used
  commit <message> [fixes] - Commits a revision with message to the bzr branch. If fixes is specified, the commit is marked to fix the bug with this number
  push [branch] - Pushes the bzr branch to branch and sets branch as default location. If no branch is specified, attempt to push to default
  addfile <file> - Adds file to the project
  removefile <file> - Removes file from the project
  clean - Removes build directory, sometimes required to have new packages used correctly

If no command is given, 'build' will be used
