Usage: beaker-hostgenerator [options] <layout>

 where <layout> takes the following form:
  <platform>-<arch>[[<arbitrary-roles>,[...]].]<roles>[{<arbitrary-settings>,[...]}][-<arch>[[<arbitrary-roles>,[...]].]<roles>[{<arbitrary-settings>,[...]}]][-<layout>]

 examples:
  centos6-64mdca-32a
   1 CentOS 6 64 bit node with roles = master, database, agent, dashboard
   1 CentOS 6 32 bit node with roles = agent

  debian8-64m-32ad-32ac-centos6-64a
   1 Debian 8 64 bit node with roles = master
   1 Debian 8 32 bit node with roles = agent, database
   1 Debian 8 32 bit node with roles = agent, dashboard
   1 CentOS 6 64 bit node with roles = agent

  debian8-64m-windows8-64a
   1 Debian 8 64 bit node with roles = master
   1 Windows 8 64 bit node with roles = agent

 example with arbitrary roles:
  centos6-32compile_master,another_role.ma
   1 CentOS 6 32 bit node with roles = master, agent, compile_master, another_role

 example with arbitrary host settings:
  centos6-64m{hypervisor=none\\,hostname=static1\\,my-key=my-value}-32a
   1 CentOS 6 64 bit node with roles = master, hypervisor = none, node name = static1, and my-key = my-value
   1 CentOS 6 32 bit node with roles = agent and the default hypervisor

 example of a list within arbitrary host settings:
  centos6-64m{hostname=static1\\,disks=[8,16],my-list=[my-value1]}-32a
   1 CentOS 6 64 bit node with roles = master, node name = static1 and lists:
  disks:
     - 8
     - 16
   my-list:
     - my-value1
   1 CentOS 6 32 bit node with roles = agent and the default hypervisor

 Generally, it is expected that beaker-hostgenerator output will be redirected to a file, for example:
  beaker-hostgenerator centos6-64ma > host.cfg

 This can then be used in a Beaker call instead of a static Beaker config.
