[parenscript-devel] Re: Merging some improvements, additions, and cleanup

[Vladimir Sedach]

Hi Travis,

That looks pretty awesome. I've asked the common-lisp.net admin to
give you an account and add you to the project. You'll need to send
your PGP public key to admin at common-lisp.net.

Out of curiosity, what kind of production system are you using Parenscript for?

Thank you,
Vladimir
