# Making a large class modular
# * Put core functionality into Base module inside your class
# * Split other functionality into modules and include them at the bottom of the
#   your class
# * Now it is easy to reuse or recreate custom versions of the class by creating
#   new classes, including only some modules, swapping modules out for others, etc.

module Remote
  # Responsible for evaluating the specification. This will transform the

  class Dsl

    # Given a string of dsl code, create a new instance of dsl and evaluate
    # the code within the context of the instance.

# This module follows best practices for daemonizing processes in a UNIX
# environment with as little fluff as possible. Forks once, calls `setsid`,
# and forks again. STDIN, STDOUT, STDERR are all redirected to /dev/null by
# default. We'll even manage the pidfile
#
# `chdir` and `umask` are optional precautions:
#
# * `chdir` is a safeguard against problems that would occur is you tried to
#   launch a daemon process on a mounted filesystem
# * `umask` gives your daemon process more control over file creation
