## A single Emacs invocation creates all the CHINESE_TIT files.
## Otherwise in a parallel build multiple Emacs instances could
## interfere with each other.  If we used GNU make we could probably
## parallelize this without the need for an explicit rule for each
## file.  Something like the pattern rule:
## quail/%.el: CXTERM-DIC/%.tit
## It doesn't seem possible to do this with VPATH and suffix rules.
