You can actually use PHP itself for this: the commandline php has a -w
option that will make it strip out all comments and whitespace.
So a simple
for f in *.php; do php -w $f > $f.tmp && mv $f.tmp $f; done
is enough to change this wc *.php:

So there is a total of 115 KB of PHP code in PEL. Zipping this gives
you a tiny-PEL of just 33 KiB.
And this is a PEL with support for all tags and features -- if you
started deleting stuff in PelTag (the long textual descriptions for
example) you end up with just 25 KiB... At this point I stopped
torturing PEL :-)
But considering how easy it is to do this automatically I will
consider distributing stripped versions of PEL. Or maybe it would be
better to include information in the README about how one can do the
stripping oneself.
