 BASIC INSTALLATION
 
-The simplest way to build Emacs is to use the `configure' shell script
-which attempts to guess correct values for various system-dependent
-variables and features and find the directories where various system
-headers and libraries are kept.  It then creates a `Makefile' in each
-subdirectory and a `config.h' file containing system-dependent
-definitions.  Running the `make' utility then builds the package for
-your system.
+On most Unix systems, you build Emacs by first running the `configure'
+shell script.  This attempts to deduce the correct values for
+various system-dependent variables and features, and find the
+directories where certain system headers and libraries are kept.
+In a few cases, you may need to explicitly tell configure where to
+find some things, or what options to use.
 
-Here's the procedure to build Emacs using `configure' on systems which
-are supported by it.  If this simplified procedure fails, or if you

-maybe perform some of the steps manually.  The more detailed
-description in the rest of the sections of this guide will help you do
