[rt-users] Replacing functions

[Tuc at T-B-O-H.NET]

Hi,

	Understood, thank you. 

	Yes, the wiki didn't seem to indicate that. I only saw
"The real RT code is in XXX_Overlay.pm.". Since the EmailParser.pm
doesn't have a _Overlay, I wasn't sure it was eligible for it.

	That xargs doesn't work on my FreeBSD, but I'll figure
that out myself.

	Thanks again.
