## net.sf.antcontrib.logic
Class Switch

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              net.sf.antcontrib.logic.Switch

    public class Switch

extends org.apache.tools.ant.Task

Task definition for the ANT task to switch on a particular value.

     Usage:

       Task declaration in the project:

         <taskdef name="switch" classname="net.sf.antcontrib.logic.Switch" />

       Task calling syntax:

         <switch value="value" [caseinsensitive="true|false"] >
           <case value="val">
             <property name="propname" value="propvalue" /> |
             <antcall target="targetname" /> |
             any other tasks
           </case>
          [
           <default>
             <property name="propname" value="propvalue" /> |
             <antcall target="targetname" /> |
             any other tasks
           </default>
          ]
         </switch>

       Attributes:
           value           -> The value to switch on
           caseinsensitive -> Should we do case insensitive comparisons?
                              (default is false)

       Subitems:
           case     --> An individual case to consider, if the value that
                        is being switched on matches to value attribute of
                        the case, then the nested tasks will be executed.
           default  --> The default case for when no match is found.

     Crude Example:

         <switch value="${foo}">
           <case value="bar">
             <echo message="The value of property foo is bar" />
           </case>
           <case value="baz">
             <echo message="The value of property foo is baz" />
           </case>
           <default>
             <echo message="The value of property foo is not sensible" />
           </default>
         </switch>
