-  * Q: How can values starting with a $ be escaped?
- 
- {{{
- #### Input
- <extensions>
-     <extension>
-         <name>Shared RCP Framework</name>
-         <href>$$context/rcp/RcpSharedWebStart.jsp</href>
-     </extension>
- </extensions>
- 
- #### Code
- #foreach( $extension in $extensions )
-     <extension name="${extension.name}" href="${extension.href}"/>
- #end
- 
- #### Output - Note the missing $ sign!
- <extension name="Shared RCP Framework" href="$context/rcp/RcpSharedWebStart.jsp"/>
- }}}
- 
- Backslash escaping like \$$context/rcp/!RcpSharedWebStart.jsp doesn't make the initial $ appear.
- 
-  * A: Help appreciated.

   * Q: How can conditionals be nested?  For example, in the equivalent of "if($a){ if($b){ b1; } else{ b2; } if($c){ c1; } else { c2; } }", where do the '#end's go?
   * A: Exactly where you put the closing parentheses in java.  So your example would be "#if( $a )#if( $b ) b1 #else b2 #end #if( $c ) c1 #else c2 #end#end".  Pretty easy.
