    longDescription = ''
      paging-calculator is a CLI utility written in Rust that helps you find the indices that a virtual
      address will have on different architectures or paging implementations.

      It takes a (virtual) address in hexadecimal format and shows you which index will be used for
      what page-table level. It can be installed with $ cargo install paging-calculator.
