This archive pre-processes the classes in JRuby to eliminate\nsome overhead at startup.\n\nBy using this utility and setting some environment variables, many\nJRuby commands can be sped up a fair amount.\n\nRunning `generate-appcds` alone will generate the AppCDS archive based\non a command line of `-e 1` as passed to JRuby. You can provide a\ndifferent command line, in quotes, to the `generate-appcds` command.\n\n```\n$ generate-appcds\n*** Outputting list of classes at /Users/headius/projects/jruby/lib/jruby.list\n...\n```\n\nWhen the command has completed, you will see some environment variables\nto set that will enable the use of the AppCDS archive.\n\n## Contributing\n\nBug reports and pull requests are welcome on GitHub at https://github.com/jruby/jruby-startup.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjruby%2Fjruby-startup","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjruby%2Fjruby-startup","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjruby%2Fjruby-startup/lists"}
