# MapServer map file uses the pound sign (#) to denote the start of a line
# comment--each line that needs to be commented has to be prepended with a "#".
#
# Map files begin with MAP keyword to signify the start of the map object.
# Well, the entire map file is THE map object.  Enclosed between MAP and END
# at the very bottom of this map file, are keyword/value pairs and other
# objects.

  # Layer objects are defined beneath the map object.  You need at least one
  # layer defined in your map file before you can display a map...  You can
  # define as many layers as you'd like.

  # Start of LAYER DEFINITIONS ---------------------------------------------
  LAYER # States polygon layer begins here

    # CLASSITEM defines the non-spatial attribute that you will be using to
    # separate a layer into classes.  This attribute will be in the DBF file
    # of your shapefile (it will be different for each data format).  In this
    # example the shapefile states_ugl has an associated database 
    # (states_ugl.dbf) that contains an attribute called "CLASS".  You will be
    # using two values in the CLASS attribute to separate the classes (also 
    # called themes) used in this layer--land and water.  CLASSITEM is used in 
    # association with the EXPRESSION parameter in the CLASS object.  See below.
    CLASSITEM    "CLASS"

    # Just like CLASSITEM, LABELITEM defines the database attribute that you 
    # will be using to draw labels.  In this case, the values of the attribute 
    # "STATE" will be used to label the states polygons.
    LABELITEM    "STATE"

    # The class object is defined within the layer object.  You can define as
    # many classes as you need.
    CLASS
      NAME 'States'
      EXPRESSION 'land'

      # There are styles in a class, just like there are classes in a layer,
      # just like there are layers in a map.  You can define multiple styles in
      # a class just as you can define multiple classes in a layer and multiple
      # layers in a map.

      # There can be labels in a class, just like there are classes in a layer,

      # layers in a map.
      # MapServer has a very flexible labeling system.  With that flexibility
      # comes complexity, specially when using truetype fonts.  Please read 
      # through the LABEL section of the MapServer map file documentation at
      # http://www.mapserver.org/mapfile for more information.
