[gentoo-user] What does xgetdefault use flag do

[Mr G]

Am I correct that the xgetdefault use flag is needed for an application if
I want it to read Xresources and Xdefaults? Does it enable anything else? I
tried searching the forum and the web but there is too many false positive
hits to sort through. Most references to it are very old so is it a
deprecated feature? The definition for the use flag is a little cryptic or
maybe I'm a little too dumb.

OT: This is my first post to this list and just want to say hi. I've been
stalking the list for several months now and this is by far the most
interesting and useful list I've ever subscribed to.
