The X Window System used imake extensively up through
the X11R6.9 release, for both full builds within
the source tree and external software. X has since
moved to GNU autoconf and automake for its build system
in X11R7.0 and later releases, but still maintains
imake for building existing external software
programs that have not yet converted.
