    mess.js is an attempt to use less.js to
    compile cascadenik-formatted styles.

    it is inspired by but incompatible with 
    Cascadenik [1].


  = Changes from Cascadenik:

    - MML files are assumed to be JSON, not XML
    - Instead of the name attribute of the TextSymbolizer
      and ShieldSymbolizer being a part of the selector, it
      is a property of a rule. Thus the evaluation is less
      complex and one can use expressions in names.

    cascadenik:
    
      #world NAME {
        text-face-name: "Arial";
      }

    mess:

      #world {
        text-name: "NAME";
        text-face-name: "Arial";
      }

    - Pseudoelements are supported to append extra
      symbolizers onto single matched rules.

    #world {
      line-color: #fff;
      line-width: 3;
      }

      #world::outline {
        line-color: #000;
        line-width: 6;
        }

    - outline and inline are removed, having been replaced
      with pseudoelements.
    - names of styles in XML are derived from layer names,
      rather than being entirely autogenerated
    - less.js variables and expressions are supported
    - fontsets are supported by simply specifying multiple
      font names


  = Credits

    mess.js is based on less.js [2], a CSS compiler
    written by Alexis Sellier. It includes
    underscore.js [3].

    like less, mess.js provides a binary in bin/,
    named mess, although it is designed primarily
    for usage as a library.

  = Usage

      messc map_file.json
