FEATURES: GemInstaller provides automated management of RubyGems. It uses a simple YAML config file to: * Automatically install the correct versions of all required gems wherever your app runs. * Automatically ensure installed gems and versions are consistent across multiple applications, machines, platforms, and environments * Automatically add correct versions of gems to the ruby load path when your app runs (‘require_gem’/‘gem’) * Automatically reinstall missing dependency gems * Automatically guess at correct platform to install for multi-platform gems * Print YAML for "rogue gems" which are not specified in the current config, to easily bootstrap your config file, or find gems that were manually installed without GemInstaller. * Avoid the "works on demo, broken on production" syndrome == SYNOPSYS: GemInstaller provides automated management of RubyGems.
