cli_doc generates HTML documentation for an application's command-line interface.

cli_doc does not need to be compiled with the application; it just needs its executable. It automatically extracts information by (recursively) calling the application with the --help option.

Currently, cli_doc supports only CLIs that are generated by clap (or applications with a similar help format).

$ cli_doc cargo

Output: doc.html
