 								  pg_top
-							 Version 3.6.1
+							 Version 4.0.0
 
 							   Mark Wong
 						and a cast of ... a few
 
 							  INSTALLATION
 
-Configuration and installation of pg_top is easy.  pg_top version 3.6
-comes with a configure script generated by gnu autoconf.  After
-unpacking the tar file, simply run "./configure".  The script will
-automatically perform a series of checks on the system and determine
-what settings are appropriate for the Makefile and certain include
-files.  Once configure completes, simply type "make install" and
-pg_top will be compiled and installed.  By default, the installation
-location is /usr/local/bin.  You can change the destination location
-with the --prefix option to configure.
+Configuring
+-----------
 
-pg_config must be in your path in order to install pg_top.
+cmake [options] CMakeLists.txt
 
-In addition to the standard options, pg_top's configure script supports
-the following:
+options:
 
-    --with-module=name
+    -DDESTDIR=PREFIX
 
-	Force the use of a particular module.  Modules are located
-	in the subdirectory "machine".  A module's name is derived
-	from the file's basename without the leading "m_".
+    Install files in PREFIX.
 
-    --with-ext=name
+    -DENABLE_COLOR=0
 
-	Compile with the extension "name", found in the subdirectory
-	"ext". At the present time, there are no extensions in the
-	standard distribution.
+    Default on.  Include code that allows for the use of color in the output
+    display.  Use -DENABLE_COLOR=0 if you do not want this feature compiled in
+    to the code.  The configure script also recognizes the spelling "colour".
 
-    --enable-debug
-    --disable-debug
+    -DENABLE_COLOR=0
 
-	Default off. Include debugging output in the compilation,
-	which can be seen with the -D switch.
+    Default on.  Include code that allows for the use of color in the output
+    display.  Use -DENABLE_COLOR=0 if you do not want this feature compiled in
+    to the code.  The configure script also recognizes the spelling "colour".
 
-    --enable-color
-    --disable-color
+    -DENABLE_KILL=0
 
-	Default on.  Include code that allows for the use of color
-	in the output display.  Use --disable-color if you do not
-	want this feature compiled in to the code.  The configure
-	script also recognizes the spelling "colour".
+    Default on.  Include code that allows for renicing and sending signals to
+    processes from within pg_top (the 'kill' and 'renice' commands). Use
+    -DENABLE_KILL=0 if you do not want this feature compiled in to the code.
 
-    --enable-kill
-    --disable-kill
+Installing
+----------
 
-	Default on.  Include code that allows for renicing and sending
-	signals to processes from within pg_top (the 'kill' and 'renice'
-	commands). Use --disable-kill if you do not want this feature
-	compiled in to the code.
