-diet glibc to statically link programs that don't need all the bloat
+diet libc to statically link programs that don't need all the bloat
 from glibc.
 
 malloc, printf and scanf contributed from Olaf Dreesen.
 
-Usage:
-	gcc -I~/dietlibc/include -Os -pipe -c *.c
-	gcc -nostdlib -o ncp ~/dietlibc/start.o *.o ~/dietlibc/dietlibc.a
+To compile:
 
-If you use the glibc includes, directory reading (and maybe other
-functions) will fail.  You have been warned!
+	$ make
+
+make should compile the diet libc itself without warnings.  In addition
+to the diet libc, the default make target includes t, which is a test
+program and probably contains code which produces warnings.  You can
+safely ignore them.
+
+When make is done, it will have created dietlibc.a in bin-i386 (or
+bin-ppc, bin-alpha, bin-sparc, bin-ppc or bin-arm, depending on your
+architecture).  In that directory you will also find a program called
+"diet", which you need to copy in a directory in your $PATH:
+
+	# install bin-i386/diet /usr/local/bin
+
+Then you can compile programs by prepending diet to the command line,
+i.e.
+
+	$ diet gcc -s -Os -pipe -o t t.c
+
+diet is cross-compiler friendly and can also be used like this:
+
+	$ diet sparc-linux-gcc -o t t.c
+
+diet will then link against dietlibc.a from bin-sparc, of course.
+diet comes with a man page (diet.1), which you can copy to an
+appropriate location, too:
+
+	# cp diet.1 /usr/local/man/man1
+
+After you compiled the diet libc successfully, I invite you to check out
+the embedded utils (http://www.fefe.de/embutils/) and the diet libc
+binary repository (ftp://foobar.math.fu-berlin.de/pub/dietlibc/), too.
+The embedded utils are small replacements for common utilities like mv,
+chown, ls, and even a small tar that can extract tar files.  The binary
+repository contains a few utilities I linked against the diet libc, for
+example gzip, bzip2 and fdisk.
