-MACHINENAME is the machine to build for. For example:
- ${progname} decstation
+CONFIGURATION specifies the machine and operating system to build for.
+For example:
+ ${progname} sparc-sun-sunos4.1
+configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
+ ${progname} decstation
configures Emacs to run on a DECstation running Ultrix. See \`etc/MACHINES'.
Options are:
--with-x, --with-x11 or --with-x10 - what window system to use;
