Plugins must be named 'rubygems_plugin' (.rb, .so, etc) and # placed at the root of your gem's #require_path. Plugins are installed at a # special location and loaded on boot. # # For an example plugin, see the {Graph gem}[https://github.com/seattlerb/graph] # which adds a <tt>gem graph</tt> command. # # == RubyGems Defaults, Packaging # # RubyGems defaults are stored in lib/rubygems/defaults.rb. If you're packaging # RubyGems or implementing Ruby you can change RubyGems' defaults. # # For RubyGems packagers, provide lib/rubygems/defaults/operating_system.rb # and override any defaults from lib/rubygems/defaults.rb. # # For Ruby implementers, provide lib/rubygems/defaults/#{RUBY_ENGINE}.rb and # override any defaults from lib/rubygems/defaults.rb. # # If you need RubyGems to perform extra work on install or uninstall, your # defaults override file can set pre/post install and uninstall hooks. # See Gem::pre_install, Gem::pre_uninstall, Gem::post_install, # Gem::post_uninstall. # # == Bugs # # You can submit bugs to the # {RubyGems bug tracker}[https://github.com/rubygems/rubygems/issues] # on GitHub # # == Credits # # RubyGems is currently maintained by Eric Hodel. # # RubyGems was originally developed at RubyConf 2003 by: # # * Rich Kilmer -- rich(at)infoether.com # * Chad Fowler -- chad(at)chadfowler.com # * David Black -- dblack(at)wobblini.net # * Paul Brannan -- paul(at)atdesk.com # * Jim Weirich -- jim(at)weirichhouse.org # # Contributors: # # * Gavin Sinclair -- gsinclair(at)soyabean.com.au # * George Marrows -- george.marrows(at)ntlworld.com # * Dick Davies -- rasputnik(at)hellooperator.net # * Mauricio Fernandez -- batsman.geo(at)yahoo.com # * Simon Strandgaard -- neoneye(at)adslhome.dk # * Dave Glasser -- glasser(at)mit.edu # * Paul Duncan -- pabs(at)pablotron.org # * Ville Aine -- vaine(at)cs.helsinki.fi # * Eric Hodel -- drbrain(at)segment7.net # * Daniel Berger -- djberg96(at)gmail.com # * Phil Hagelberg -- technomancy(at)gmail.com # * Ryan Davis -- ryand-ruby(at)zenspider.com # * Evan Phoenix -- evan(at)fallingsnow.net # * Steve Klabnik -- steve(at)steveklabnik.com # # (If your name is missing, PLEASE let us know!) # # == License # # See {LICENSE.txt}[https://github.com/rubygems/rubygems/blob/master/LICENSE.txt] for permissions. # # Thanks! # # -The RubyGems Team module Gem RUBYGEMS_DIR = __dir__ ## # An Array of Regexps that match windows Ruby platforms.
