     * RECOGNIZED OPTIONS:
     * Define the Automatic Task Tags
     *    When the tag list is not empty, indexer will issue a task marker whenever it encounters
     *    one of the corresponding tags inside any comment in C/C++ source code.
     *    Generated task messages will include the tag, and range until the next line separator or comment ending.
     *    Note that tasks messages are trimmed. If a tag is starting with a letter or digit, then it cannot be leaded by
     *    another letter or digit to be recognized ("fooToDo" will not be recognized as a task for tag "ToDo", but "foo#ToDo"
     *    will be detected for either tag "ToDo" or "#ToDo"). Respectively, a tag ending with a letter or digit cannot be followed
     *    by a letter or digit to be recognized ("ToDofoo" will not be recognized as a task for tag "ToDo", but "ToDo:foo" will
     *    be detected either for tag "ToDo" or "ToDo:").
     *     - option id:         "org.eclipse.cdt.core.taskTags"
     *     - possible values:   { "<tag>[,<tag>]*" } where <tag> is a String without any wild-card or leading/trailing spaces 
     *     - default:           ""
     * 
     * Define the Automatic Task Priorities
     *    In parallel with the Automatic Task Tags, this list defines the priorities (high, normal or low)
     *    of the task markers issued by the translation.
     *    If the default is specified, the priority of each task marker is "normal".
     *     - option id:         "org.eclipse.cdt.core.taskPriorities"
     *     - possible values:   { "<priority>[,<priority>]*" } where <priority> is one of "high", "normal" or "low"
     *     - default:           ""
