[ANN] ETag include for On-Rev (was Re: Compare files between on-rev and local versions)

[Andre Garzia]

Stephen,
if you go to your on-rev client preferences, you can set it to edit .inc

I am not using the client for my developments, I use it only for debugging.
I do all my dev using TextMate and Interarchy.

:D
