Re: LuaPlus

["Dylan Cuthbert" <dylan@...>]

Sorry about the font, not sure why its crappy looking on your screen - I'm
posting in plain text but "charset="iso-2022-jp" is in the message header
because I used the japanese version of Outlook I suppose.

So you are the man behind LuaPlus, ok, what I meant by LuaBind being better
supported was by comparing the home pages, LuaBind is very slick for some
reason, and also a lot of the stuff at the bottom of the LuaPlus home page
says "obsolete" etc.  Also I couldn't find an e-mail address or your name
even so I didn't know where to go to ask questions.  :-)  But it sounds like
you're pretty active.  Do you have a mailing list or do you simply answer
questions on a person-to-person basis?

Any ideas regarding this vector thing I'm working on?  ;-)
