+Set compilation and installation parameters for GNU Emacs, and report.
+MACHINENAME is the machine to build for.  See \`etc/MACHINES'.
+Options are:
+  -opsystem=SYSTEM - operating system to build for; see \`etc/MACHINES'.
+  -libroot=DIR - where to install Emacs's library files
+These options have reasonable defaults (in []s), and may not be needed:
+  -g, -O - Passed to the compiler.  If omitted, use -O only.
+  -cc=COMPILER - Which compiler to use.  Defaults to gcc if available.
+  -libdir=DIR - where to look for arch-dependent library files
+  -datadir=DIR - where to look for architecture-independent library files
+  -installbin=DIR - where to install the Emacs executable, and some friends
+  -lisppath=PATH - colon-separated list of Elisp directories
+  -lockdir=DIR - where Emacs should do its file-locking stuff
+  -window_system=none or [x11, if it is installed] - what window system to use
+  -have_x_menu=yes or [no] - include menu support under X11
+  -gnu_malloc=[yes] or no - use the GNU memory allocator
+  -rel_alloc=[yes] or no - use compacting allocator for buffers
+  -highpri=N - run at N points higher-than-normal priority
+  -lisp_float_type=[yes] or no - Support floating point in Elisp
+If successful, ${progname} leaves its status in config.status.  If
+unsuccessful after disturbing the status quo, config.status is removed."
