Re: [ANN] VStruct, the versatile struct library - 1.0 beta 1

["Peter Cawley" <lua@...>]

My first bash at a floating point module for this:
http://www.corsix.org/misc/fp.lua
Place in the same folder as read.lua / write.lua and add:
local fp = require (name..".fp")
to the start of those two files, after the other require statements
