       rackup

       rackup(1) -- An utility for run Rack-based applications

SYNOPSIS

       rackup [ruby options] [rack options] [rackup config]

DESCRIPTION

       Rackup is a useful tool for running Rack applications, which uses the Rack::Builder DSL to
       configure middleware and build up applications easily.

       rackup automatically figures out the environment it is run in, and runs  your  application
       as FastCGI, CGI, or standalone with Mongrel or WEBrick -all from the same configuration.
