                            ## it for sandboxing)

  the possible messages Source Edit

    MsgHandler = proc (filename: string; line, col: int; msgKind: MsgKind; arg: string) {...}{.
        closure, gcsafe.}

  what to do in case of an error Source Edit

    FindFileHandler = proc (filename: string): string {...}{.closure, gcsafe.}

    EParseError = object of ValueError

# Procs

    proc whichMsgClass(k: MsgKind): MsgClass {...}{.raises: [], tags: [].}

  returns which message class `k` belongs to. Source Edit

    proc defaultMsgHandler(filename: string; line, col: int; msgkind: MsgKind; arg: string) {...}{.
        procvar, raises: [ValueError, EParseError, IOError], tags: [WriteIOEffect].}

  Source Edit

    proc defaultFindFile(filename: string): string {...}{.procvar, raises: [],
        tags: [ReadDirEffect].}

  Source Edit

    proc addNodes(n: PRstNode): string {...}{.raises: [], tags: [].}

  Source Edit

    proc rstnodeToRefname(n: PRstNode): string {...}{.raises: [], tags: [].}

  Source Edit

    proc getFieldValue(n: PRstNode): string {...}{.raises: [], tags: [].}

  Returns the value of a specific `rnField` node.

  This proc will assert if the node is not of the expected type. The empty string will be returned as a minimum. Any value in the rst will be stripped form leading/trailing whitespace.

                 msgHandler: MsgHandler = nil): PRstNode {...}{.raises: [Exception],
