[MM_Siddique <mms@xxxxxxxxxxxxxxxxxxxxx>]

# Any additions from configure.in:
ac_help="$ac_help
--with-opts-prefix=PFX Prefix where autoopts is installed (optional)"
ac_help="$ac_help
--with-opts-exec-prefix=PFX
Exec prefix where autoopts is installed (optional)"


# Check whether --with-opts-prefix or --without-opts-prefix was given.
if test "${with_opts_prefix+set}" = set; then
withval="$with_opts_prefix"
:
fi

# Check whether --with-opts-exec-prefix or --without-opts-exec-prefix 
was given.
if test "${with_opts_exec_prefix+set}" = set; then
withval="$with_opts_exec_prefix"
:
fi


# Check whether --enable-opts-test or --disable-opts-test was given.
if test "${enable_opts_test+set}" = set; then
enableval="$enable_opts_test"
:
fi


if test x$with_opts_exec_prefix != x ; then
autoopts_config_args="$autoopts_config_args 
--exec-prefix=$with_opts_exec_prefix"
if test x${AUTOOPTS_CONFIG+set} != xset ; then
AUTOOPTS_CONFIG=$with_opts_exec_prefix/bin/autoopts-config
fi
fi
if test x$with_opts_prefix != x ; then
autoopts_config_args="$autoopts_config_args --prefix=$with_opts_prefix"
if test x${AUTOOPTS_CONFIG+set} != xset ; then
AUTOOPTS_CONFIG=$with_opts_prefix/bin/autoopts-config
fi
fi
