I am wondering if we could have a pdf file, which can tell what viewer its being viewed with. I was looking for some tex command, which says something like:
If viewer is Acrobat, print "Hi You are viewing this file in acrobat" Else, print "Hi you are not using acrobat".
The reason I need this is because I am using some tex features that require the pdf viewer to have java enabled. So, when the viewer being used is not java enables, the pdf must contain "View this file in Acrobat Reader" .
Is there any macro in any package for detecting if the pdf viewer being used is Acrobat Reader or not.
I hope I am clear.
