In general, $$ means translates to a single $ which will not be interpreted
as the possible start of a property, so use:
	<echo message="$${theproperty}" />

| 
| 
| Hi,
| 
| There is a situation where I want to use "${property.name}" instead of
| the value it stands for.  How do I tell Ant to not interpret it?
| 
| For example, I want
|      <property name="theproperty" value="thevalue" />
|     <echo message="${theproperty}" />
| to say ${theproperty} instead of "thevalue".
| 
| This works when the property was never set.  I understand that
| "unsetting" a property is a feature that Ant does not have.
| 
| I know that a <param> in an <antcall> overrides a property of the same
| name, but I don't think there is a magic value to set it to for the
| called target to think it is not set.
| 
| I know that using inheritAll="false" on <antcall> does exactly what I
| want, except for all properties.
| 
| Is there an "escape code" or other such thing to specify a literal
| string vs interpreting it?
