 * - AutotoolsManager: Will manage the new autotools project and
 *   tell QtCreator for which MIME types the autotools project should
 *   be instantiated.
 *
 * - MakeStepFactory: This factory is used to create make steps.
 *
 * - AutogenStepFactory: This factory is used to create autogen steps.
 *
 * - AutoreconfStepFactory: This factory is used to create autoreconf
 *   steps.
 *
 * - ConfigureStepFactory: This factory is used to create configure steps.
 *
 * - MakefileEditorFactory: Provides a specialized editor with automatic
 *   syntax highlighting for Makefile.am files.
 *
 * - AutotoolsTargetFactory: Our current target is desktop.
 *
 * - AutotoolsBuildConfigurationFactory: Creates build configurations that
 *   contain the steps (make, autogen, autoreconf or configure) that will
 *   be executed in the build process)
