This is a summary.
This is a description.
COMMENT;

            // to prevent parsing issues
            $comment = preg_replace('/\h*$/Sum', '', $comment);

            /*
             * Splits the docblock into a short description, long description and
             * tags section
             * - The short description is started from the first character until
             *   a dot is encountered followed by a newline OR
             *   two consecutive newlines (horizontal whitespace is taken into
             *   account to consider spacing errors)
             * - The long description, any character until a new line is
             *   encountered followed by an @ and word characters (a tag).
             *   This is optional.
             * - Tags; the remaining characters
             *
