# 20200524 bkw:
# - take over maintenance, BUILD=2
# - add partial 64-bit support (olwm and olvwm work, apps don't)
# - add xinitrc.ol[v]wm
# - add MAKEFLAGS=-j1
# - remove XVIEW_BROKEN_X11_WORKAROUND from README, not needed on 14.2

************************************************************************
Warning: xview doesn't fully support 64-bit systems. The window managers
(olwm and olvwm) work, but the applications (olclock, oledit, etc) crash
on startup. Please don't report this as a bug, we already know.
Press Enter or wait 5 seconds to continue, or press ^C to abort.
