- I've worked a lot with the PHP templating system, Smarty, and I've adapted it's \
handy debugging console for Velocity. + This console will display a popup window with \
information about all of the variables available in the Velocity Context.  It can be \
an invaluable debugging tool.  
-  Put the code below into a template called "debug.vm", and #parse it at the end of \
the template you want to debug (after the </html> tag). It will pop up a window with \
all of the context variables in it, so you can see what is being passed to your \
template.  (Thanks to Dan Chapman for working on this as well). + To use, either add \
this pair of macros to your template, or better yet, to your VM_Global_library.vm \
file.  Then from the template you want to debug, you can simply add #showDebugPopup() \
to the bottom of the template you want to debug, and it will pop up a window with \
debugging information.  You'll need to remove that invocation before you go to \
production. :)  
-  Enjoy!

  Here is the latest version, which uses the ContextTool.  You must have access to \
the Context Tool as $context for this to work.  There is a version below this that \
does not require that.  This newer version also removes any variables that are \
                invalid VTL.
