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

Overwrite an existing output file
The output file must have the .cxx, .C, .cpp, .cc or .cp extension.
Display all messages
Display no messages at all
Display only error messages
Display error and warning messages (default).
Display error, warning and note messages
Display all messages
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
Rootmap file name
Name of the rootmap file. In order to be picked up by ROOT it must
have .rootmap extension
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 the dictionary
Split the dictionary in two, putting the ClassDef functions in a separate
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

Enable support for multiple pcms in one library
Needs the -s flag. See its documentation.
Add the argument header to the code of the dictionary
This allows the header to be inlined within the dictionary
No IO information in the dictionary
Do not store the headers' directories in the dictionary
Instead, rely on the environment variable $ROOT_INCLUDE_PATH at runtime
Specify a path to be excluded from the include paths
specified for building this dictionary
Specify libraries needed by the header files parsed
This feature is used by ACliC (the automatic library generator).
Rootcling will read the content of 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
