@MAINT@# I define $(autoconf) to acgeneral.m4 and the other Autoconf files, so
@MAINT@# configure automatically gets remade in the sources with a new Autoconf
@MAINT@# release.  But it would be bad for installers with Autoconf to remake
@MAINT@# configure (not to mention require Autoconf), so I take out the variable
@MAINT@# $(autoconf) definition before release.
@MAINT@# 
@MAINT@# BTW, xt.ac isn't really required for dvipsk or dviljk, but it doesn't
@MAINT@# seem worth the trouble.

# This rule isn't used for the top-level Makefile, but it doesn't hurt.
