## net.sf.antcontrib.property
Class PropertyCopy

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              net.sf.antcontrib.property.AbstractPropertySetterTask
                  net.sf.antcontrib.property.PropertyCopy

    public class PropertyCopy

extends AbstractPropertySetterTask

Task definition for the propertycopy task, which copies the value of a named property to another property. This is useful when you need to plug in the value of another property in order to get a property name and then want to get the value of that property name.

     Usage:

       Task declaration in the project:

         <taskdef name="propertycopy" classname="net.sf.antcontrib.property.PropertyCopy" />

       Call Syntax:

         <propertycopy name="propname" from="copyfrom" (silent="true|false")? />

       Attributes:
         name      --> The name of the property you wish to set with the value
         from      --> The name of the property you wish to copy the value from
         silent    --> Do you want to suppress the error if the "from" property
                       does not exist, and just not set the property "name".  Default
                       is false.

       Example:
         <property name="org" value="MyOrg" />
         <property name="org.MyOrg.DisplayName" value="My Organiziation" />
         <propertycopy name="displayName" from="org.${org}.DisplayName" />
         <echo message="${displayName}" />
