Initial value:

                                  = R"(
Add directories in ROOT files
 
positional arguments:
  FILE:path             File(s) and path(s) of directories to create
 
options:
  -h, --help            get this help
  -p, --parents         create parent directories if needed, no error if directory already exists
  -v, --verbose         be verbose (can be repeated for increased verbosity)
 
Note that calling rootmkdir without a directory path can be used to create files (similar to the `touch` command).
You can also simultaneously create files and directories in it if you pass the -p flag.
 
examples:
- rootmkdir example.root:dir
  Add the directory 'dir' to the ROOT file 'example.root' (file must exists)
 
- rootmkdir example.root:dir1/dir2
  Add the directory 'dir2' in 'dir1' which exists in the ROOT file 'example.root'
 
- rootmkdir -p example.root:dir1/dir2/dir3
  Make parent directories of 'dir3' as needed, no error if target directory already exists
 
- rootmkdir non_existent.root
  Create an empty ROOT file named 'non_existent.root'
 
- rootmkdir -p non_existent.root:dir1
  Create a ROOT file named 'non_existent.root' and directory `dir1` in it
