> Generating the nodetool AsciiDoc documentation is slow as the 
> gen-nodetool-docs script uses the nodetool command-line wrapper to capture 
> help text for eac command. Each invocation starts a brand-new jvm, so 
> building the documentation incurs the jvm startup cost over a hundred times 
> (100+ node tool commands). 
> This makes the documentation build unnecessarily slow and ties it to the 
> shell wrapper and its environment setup. The solution: Generate the raw 
> {{nodetool help}} text for every command in a single jvm.
