    "\h|SYNOPSIS|

     \c{\b{bpkg cfg-create}|\b{create} [<options>] [<cfg-args>]\n
        \b{bpkg cfg-create}|\b{create} [<options>] \b{--existing|-e}}

     \c{<cfg-args> = (<module> | <cfg-var>)...}

     \h|DESCRIPTION|

     The \cb{cfg-create} command creates a new \cb{bpkg} configuration with
     the specified \cb{build2} modules and configuration variables (the first
     form) or initializes one based on an existing build system configuration
     (the second form). The \cb{bpkg} configuration itself is a build system
     configuration; see build system driver (\l{b(1)}) \cb{create}
     meta-operation for details.

     Unless the \cb{--existing|-e} or \cb{--wipe} option is specified,
     \cb{cfg-create} expects the configuration directory to be empty or to not
     exist (in which case it will be created).

     By default, the configuration created with the first form loads the
     \cb{config}, \cb{test}, \cb{dist}, and \cb{install} modules. However,
     additional modules and, if required, their configuration variables can be
     specified as the \cb{cfg-create} arguments. For example:

     \
     bpkg create cxx config.cxx=clang++ config.install.root=/usr/local
     \

     By default, \cb{bpkg} appends \cb{.config} to the names of the modules
     that you specify so that only their configurations are loaded. You can
     override this behavior by specifying the period (\cb{.}) after the module
     name. You can also instruct \cb{bpkg} to use the optional module load by
     prefixing the module name with the question mark (\cb{?}). For example:

     \
     bpkg create cxx. \"?cli\"
     \
     "
  }

  class cfg_create_options: common_options
  {
    "\h|CFG-CREATE OPTIONS|"

    dir_path --directory|-d (".")
    {
      "<dir>",
      "Create the configuration in <dir> rather than in the current working
       directory."
    }

    bool --existing|-e
    {
      "Initialize a \cb{bpkg} configuration based on an existing build system
       configuration."
    }

    bool --wipe
    {
      "Wipe the configuration directory clean before creating the new
       configuration. For safety, this option requires that you specify the
       configuration directory explicitly with \cb{--directory|-d}."
    }
  };

   \h|DEFAULT OPTIONS FILES|

   See \l{bpkg-default-options-files(1)} for an overview of the default
   options files. For the \cb{cfg-create} command the search start directory
   is the parent directory of the new configuration. The following options
   files are searched for in each directory and, if found, loaded in the
   order listed:

   \
   bpkg.options
   bpkg-cfg-create.options
   \

   The following \cb{cfg-create} command options cannot be specified in the
   default options files:

   \
   --directory|-d
   --wipe
   \
