Good question.
I want to  parse config files from /etc,  for example,
	/etc/network/interfaces
	/etc/dnsmasq.conf
	/etc/resolv.conf
	/etc/modules
	/etc/ssh/sshd_config
I have no control over the format, and there are plenty of different 
formats.  I then want to process the parsed tree with Lua.

The easiest way out of that problem is appears to be:

A) Use someone else's filter (and bind it to Lua)
B) Rewrite someone else's filter in Lua
C) Roll your own filter in Lua

Of the three options, A seems the least amount of work (and thus the 
original question)

Hope that helps.
