<<-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. When done, it will generate a set of files like this:
gems/ # .gem files you want to index
quick/index
quick/index.rz # quick index manifest
quick/<gemname>.gemspec.rz # legacy YAML quick index file
quick/Marshal.<version>/<gemname>.gemspec.rz # Marshal quick index file
Marshal.<version>
Marshal.<version>.Z # Marshal full index
yaml
yaml.Z # legacy YAML full index
The .Z and .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. The
yaml indexes exist for legacy RubyGems clients and fallback in case of Marshal
version changes.
