<<-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.
