+dnl Public domain. Originally written many years ago by Karl Berry and
+dnl Thomas Esser, and others.
+dnl
+dnl Top-level configure for kpathsea-using programs.
+dnl Our job is to run configure in the relevant subdirectories.
+dnl
+dnl Assumption: each program will create a c-auto.h that defines
+dnl everything kpathsea needs. We arrange this by including (at
+dnl autoconf time) kpathsea/common.ac.
+dnl
+dnl Consequence: we don't need to run configure in the kpathsea directory
+dnl itself; we can just copy from a program directory. We'll use the
+dnl first one.
+dnl
+AC_INIT(kpathsea/kpathsea.texi)
+
+dnl These configure scripts won't work with anything else.

+
+dnl If we guessed the prefix in the subdirectories, it might guess
+dnl differently than the prefix here, and that would cause confusion.
+AC_PREFIX_PROGRAM(tex)
+
+dnl Pass this down from the top level so that when the subprograms
+dnl install kpathsea a command line value is propagated.
+AC_PROG_INSTALL
+
+dnl If the other programs ever acquire their own --with or --enable
+dnl options, they must be added, so configure --help at the top level
+dnl will show all the options.
