def description # :nodoc:
  <<-EOF
The generate_index command creates a set of indexes for serving gems
statically.  The command expects a 'gems' directory under the path given to
the --directory option.  The given directory will be the directory you serve
as the gem repository.

For `gem generate_index --directory /path/to/repo`, expose /path/to/repo via
your HTTP server configuration (not /path/to/repo/gems).

When done, it will generate a set of files like this:

gems/*.gem                                   # .gem files you want to
                                             # index

specs.<version>.gz                           # specs index
latest_specs.<version>.gz                    # latest specs index
prerelease_specs.<version>.gz                # prerelease specs index
quick/Marshal.<version>/<gemname>.gemspec.rz # Marshal quick index file

The .rz extension files are compressed with the inflate algorithm.
The Marshal version number comes from ruby's Marshal::MAJOR_VERSION and
Marshal::MINOR_VERSION constants.  It is used to ensure compatibility.
