/**
 * Offers a "GitPorcelain"-like API to interact with a git repository.
 * <p>
 * The GitPorcelain commands are described in the <a href=
 * "http://www.kernel.org/pub/software/scm/git/docs/git.html#_high_level_commands_porcelain"
 * >Git Documentation</a>.
 * <p>
 * This class only offers methods to construct so-called command classes. Each
 * GitPorcelain command is represented by one command class.<br>
 * Example: this class offers a {@code commit()} method returning an instance of
 * the {@code CommitCommand} class. The {@code CommitCommand} class has setters
 * for all the arguments and options. The {@code CommitCommand} class also has a
 * {@code call} method to actually execute the commit. The following code show's
 * how to do a simple commit:
 *
 * <pre>
 * Git git = new Git(myRepo);
 * git.commit().setMessage(&quot;Fix393&quot;).setAuthor(developerIdent).call();
 * </pre>
 *
 * All mandatory parameters for commands have to be specified in the methods of
 * this class, the optional parameters have to be specified by the
 * setter-methods of the Command class.
 * <p>
 * This class is intended to be used internally (e.g. by JGit tests) or by
 * external components (EGit, third-party tools) when they need exactly the
 * functionality of a GitPorcelain command. There are use-cases where this class
 * is not optimal and where you should use the more low-level JGit classes. The
 * methods in this class may for example offer too much functionality or they
 * offer the functionality with the wrong arguments.
