  And I have a few examples of LPeg use here:

	https://github.com/spc476/LPeg-Parsers

  Start with ip.lua, specifically IPv4.  It's probably the easiest
production to start with (it matches an IPv4 address, and returns it as a
four-byte network address in network byte order).  The IPv6 production looks
intimidating, but it's really quite straightforward, if a bit of a
brute-force parsing of IPv6 addresses (it returns a 16-byte address in
network-byte order).

  Both email.lua and json.lua use the re module extensively.  I find re to
be a bit more readable than raw LPeg but that's me.
