DESCRIPTION
This program generates the dictionaries needed for performing I/O of classes.

OPTIONS

-f  Overwrite an existing output file

    The output file must have the .cxx, .C, .cpp, .cc or .cp extension.

-v  Display all messages

-v0 Display no messages at all

-v1 Display only error messages

-v2 Display error and warning messages (default).

-v3 Display error, warning and note messages

-v4 Display all messages

-m  Specify absolute or relative path Clang pcm file to be loaded

    The pcm file (module) produced by this invocation of rootcling

    will not include any of the declarations already included in the

    pcm files loaded via -m. There can be more than one -m

-rmf
    Rootmap file name

    Name of the rootmap file. In order to be picked up by ROOT it must

    have .rootmap extension

-rml
    Rootmap library name

    Specify the name of the library which contains the autoload keys. This

    switch can be specified multiple times to autoload several libraries in

    presence of a particular key

-split
    Split the dictionary

    Split the dictionary in two, putting the ClassDef functions in a separate

    file

-s  Target library name

    The flag -s must be followed by the name of the library that will

    contain the object file corresponding to the dictionary produced by

    this invocation of rootcling.

    The name takes priority over the one specified for the rootmapfile.

    The name influences the name of the created pcm:

       1) If it is not specified, the pcm is called libINPUTHEADER_rdict.pcm

       2) If it is specified, the pcm is called libTARGETLIBRARY_rdict.pcm

          Any "liblib" occurence is transformed in the expected "lib"

       3) If this is specified in conjunction with --multiDict, the output is

          libTARGETLIBRARY_DICTIONARY_rdict.pcm

-multiDict
    Enable support for multiple pcms in one library

    Needs the -s flag. See its documentation.

-inlineInputHeader
    Add the argument header to the code of the dictionary

    This allows the header to be inlined within the dictionary

-interpreteronly
    No IO information in the dictionary

-noIncludePaths
    Do not store the headers' directories in the dictionary

    Instead, rely on the environment variable $ROOT_INCLUDE_PATH at runtime

-excludePath
    Specify a path to be excluded from the include paths

    specified for building this dictionary

--lib-list-prefix
    Specify libraries needed by the header files parsed

    This feature is used by ACliC (the automatic library generator).

    Rootcling will read the content of xxx.in for a list of rootmap files (see

    rlibmap). Rootcling will read these files and use them to deduce a list of

    libraries that are needed to properly link and load this dictionary. This

    list of libraries is saved in the first line of the file xxx.out; the

    remaining lines contains the list of classes for which this run of

    rootcling produced a dictionary
