#' Bioconductor Binary Repository Statistics
#'
#' @aliases print.repositoryStats
#'
#' @description Summarize binary packages compatible with the Bioconductor or
#' Terra container in use.
#'
#' @param version (Optional) `character(1)` or `package_version`
#' indicating the _Bioconductor_ version (e.g., "3.8") for which
#' repositories are required.
#'
#' @param binary_repository `character(1)` location of binary repository as
#' given by `BiocManager::containerRepository` (default)
#'
#' @param ... further arguments passed to or from other methods (not used).
#'
#' @return a list of class `repositoryStats` with the following fields:
#' * container: `character(1)` container label, e.g.,
#' `bioconductor_docker`, or NA if not evaluated on a supported container
#' * bioconductor_version: `package_version` the
#' Bioconductor version provided by the user.
#' * repository_exists: `logical(1)` TRUE if a binary repository
#' exists for the container and Bioconductor_Version version.
#' * bioconductor_binary_repository: `character(1)` repository
#' location, if available, or NA if the repository does not exist.
#' * n_software_packages: `integer(1)` number of software packages
#' in the Bioconductor source repository.
#' * n_binary_packages: `integer(1)` number of binary packages
#' available. When a binary repository exists, this number is likely
#' to be larger than the number of source software packages, because
#' it includes the binary version of the source software packages, as
#' well as the (possibly CRAN) dependencies of the binary packages
#' * n_binary_software_packages: `integer(1)` number of binary
#' packages derived from Bioconductor source packages. This number is
#' less than or equal to `n_software_packages`.
#' * missing_binaries: `integer(1)` the number of Bioconductor
#' source software packages that are not present in the binary
#' repository.
#' * out_of_date_binaries: `integer(1)` the number of Bioconductor
#' source software packages that are newer than their binary
#' counterpart. A newer source software package
#' might occur when the main Bioconductor build system has
#' updated a package after the most recent run of the binary
#' build system.
