+Ranges
+
+ Description:
+   Ranges are defined as a start and end point on a numeric scale.  The
+   generalized format for a range is:
+
+   [@]start:end
+
+   Ranges are normally considered to be exclusive and the check will fail
+   when outside the range.  If the range starts with @, then the check will
+   be inclusive and the check will fail when inside the range.  If start = 0,
+   then start and : are not required.  If range is in the format of start:,
+   then end is assumed to be infinity.  To specify negative infinity use ~.
+
+   For simple boolean checks, you should specify what you want to fail.  For
+   example, warning = true will fail when the result is true.  If warning =
+   false the check will fail when the result is false.
+
+ Examples:
+   10      =  alert when < 0 or > 10     | outside range of { 0..10 }
+   10:     =  alert when < 10            | outside range of { 10..Infinity }
+   ~:10    =  alert when > 10            | outside range of { -Infinity..10 }
+   10:20   =  alert when < 10 OR > 20    | outside range of { 10..20 }
+   @10:20  =  alert when >= 10 AND <= 20 | inside  range of { 10..20 }
+   true    =  alert when true
+   false   =  alert when false
