  # WELCOME TO WARTHOG
  
  I does build decisions.
  
  ## Usage
  
  ```
  use System::Query;
  use JSON::Fast;
  
  my $json      = from-json("build.json".IO.slurp);
  my $decisions = system-collapse($json);
  
  qw<...>;
  
  ```
  
  ## Input
  
  Calling `parse` with the following JSON will run through and choose what it thinks is the best options in the environment.
  
  ```
  {
    "nested": {
      "test": "data"
    },
    "nested2": {
      "test2": "data2"
    },
    "options": {
      "run": {
        "by-distro.name": {
          "macosx": {
            "by-distro.version": {
              "10.0+": "10make",
              "9.0+": "9make",
              "8.0+": "8make"
            }
          },
          "win32": {
            "by-distro.version": {
              "6+": "6winmake",
              "5+": "5winmake" 
            }
          },
          "": "null-make"
        }
      }
    },
    "default-test": {
      "second-test": "string-val, no decisions",
      "first-test": {
        "by-distro.name": {
          "": "default-option1"
        }
      }
    }
  }
  
  ```
  
  ## Output
  
  This is the result of the parse; notice that the distro/kernel/etc queries collapse to show the decisions based on variables.
  
  ```
  {
    default-test => {
      first-test  => "default-option1".Str,
      second-test => "string-val, no decisions".Str,
    },
    nested       => {
      test => "data".Str,
    },
    nested2      => {
      test2 => "data2".Str,
    },
    options      => {
      run => "10make".Str,
    },
  }
  
  ```
