+## The Emacs repository does not include the configure script (and

## For more details, see the file INSTALL.REPO.
## Tools we need:
## Note that we respect the values of AUTOCONF etc, like autoreconf does.
-progs="autoconf automake pkg-config"
+progs="autoconf automake"
## Minimum versions we need:
autoconf_min=`sed -n 's/^ *AC_PREREQ(\([0-9\.]*\)).*/\1/p' configure.ac`
## AM_INIT_AUTOMAKE call.
automake_min=`sed -n 's/^ *AM_INIT_AUTOMAKE(\([0-9\.]*\)).*/\1/p' configure.ac`
-pkg_config_min=`sed -n 's/^ *PKG_PROG_PKG_CONFIG(\([0-9\.]*\)).*/\1/p' configure.ac`
## $1 = program, eg "autoconf".
## Echo the version string, eg "2.59".
