# There are three ways xorg might be installed relative to extension: via a
# dependency before extension, via explicit selection before extension, and via
# explicit selection after extension.
# The first is handled by checking XMETHOD, as the first X11 backend brought in
# (explicit or otherwise) sets XMETHOD permanently.  The latter two are handled
# by greping the explicit targets file for xorg.
