	`compute(self, overwrite)` Compute the features for all file in the directory tree.
	`enable_log(self, on_screen, logfile)` Enable/disable the logs on the screen and/or on file.
	`log(self, msg)` Log the given message.
	`log_info(self)` Log general informations about the current system.
	`log_options(self, options, text)` Log the given options.
	`set_cmd(self, cmd, options)` Set the commands and options to use for convert into features.
	`set_dirs(self, from_dir, to_dir, from_ext, to_ext, bin_dir)` Set the used directories.
	`_convert(self, (from_dir, to_dir, overwrite), dir, files)` Internal method called for each file to convert.
