    /** Invokes the comment block parser with the request to parse a
     *  single comment block.
     *  @param[in] parser The language parse that invoked this function.
     *         The comment block parse may invoke
     *         ParserInterface::parsePrototype() in order to parse
     *         the argument of a @@fn command.
     *  @param[in] curEntry The Entry to which the comment block belongs.
     *         Any information (like documentation) that is found in
     *         the comment block will be stored in this entry.
     *  @param[in] comment A string representing the actual comment block.
     *         Note that leading *'s are already stripped from the comment block.
     *  @param[in] fileName The name of the file in which the comment is found.
     *         Mainly used for producing warnings.
     *  @param[in,out] lineNr The line number at which the comment block was found.
     *         When the function returns it will be set to the last line parsed.
     *  @param[in] isBrief TRUE iff this comment block represents a brief description.
     *  @param[in] isJavadocStyle TRUE iff this comment block is in "Javadoc" style.
     *         This means that it starts as a brief description until the end of
     *         the sentences is found and then proceeds as a detailed description.
     *  @param[in] isInbody TRUE iff this comment block is located in the body of
     *         a function.
     *  @param[in,out] prot The protection level in which this comment block was
     *         found. Commands in the comment block may override this.
     *  @param[in,out] position The character position within \a comment where the
     *         comment block starts. Typically used in case the comment block
     *         contains multiple structural commands.
     *  @param[out] newEntryNeeded Boolean that is TRUE if the comment block parser
     *         finds that a the comment block finishes the entry and a new one
     *         needs to be started.
     *  @param[in] markdownEnabled Indicates if markdown specific processing should be done.
     *  @returns TRUE if the comment requires further processing. The
     *         parameter \a newEntryNeeded will typically be true in this case and
     *         \a position will indicate the offset inside the \a comment string
     *         where to proceed parsing. FALSE indicates no further processing is
     *         needed.
