Subject Re: Parsing error... ?#~

Wow, that was indeed the problem -- it had caught me unawares....

Funny enough, our code was originally implemented with the

         velocimacro.library = <library1>,<library2>,<library3>...

construct, but the Velocity singleton limitation forced me to be "creative" 
and I moved to using the #parse construct -- unfortunately, I butted up 
against this unexpected side-effect.   At least now I know... :)

Thanks for all your insights...

Take care,
