 LCDproc is in fact two things, a client (lcdproc) and a server (LCDd).
 The client gathers informations and sends them to the server.
+
 The server displays the informations on an LCD display.
 The client and the server use a TCP connection to communicate, so it is
 possible to have a client on a box in Sweden showing its stats on a LCD
-display in the United States. For hardware reasons, the client is much 
-more portable than the server. Here's are the prerequistes for both:

+Many different displays (or better said: output devices) are supported.
+Some of these devices also support input, for example with a keypad.
+There are drivers for input-only devices too.

-Connecting the display to your system
+For LCDd (the server) to use the device, it needs to load a driver. The
+drivers are so called 'shared modules', that usually have an extension
+of .so . The drivers to be loaded should be specified in the config file
+(by one or more Driver= lines), or on the command line. The command line
+should only be used to override things in the config file. The drivers
+should be in a directory that is indicated by the DriverPath= line in
+the configfile.

 Depending on what kind of LCD display that you have, there are several
 sources for informations. If your LCD display came with a manual, this
-is a great place to start. If you don't have a manual, then you must find
-out what kind of display this is, and check the related informations:

 -- PLATFORM SPECIFIC ------------------------------------------------

+The lcdproc crew has tried to support a number of platforms. Platforms
+that are very non-standard are not and will probably never be supported.
+Both server & drivers and clients have their own difficulties in
+porting. Here's are the prerequistes for both:
+
+--- Client ---
+The client should run on any POSIX compliant system.

+architecture. It has been sucessfully tested on:
+Linux 2.2.x, Linux 2.4.x, NetBSD 1.5, OpenBSD 3.0
+
 Here are some comments specific to each platform that LCDproc has been
 tested on.

 --- Linux ---
 Nothing special to say, everything should go well.

-You may be able to compile the server on something else than i386 if your
-linux installation can emulate ioperm, inb and outb commands. I heared 
-that some Alpha do that.
+You may not be able to compile all drivers on something else than i386
+if your linux installation does not have ioperm, inb and outb commands.
+I heared that some Alpha do that. You can leave all parallel port
+drivers out and it should compile again.

 --- NetBSD ---
-You need to use GUN Make instead of NetBSD's make. 
-You can find a GNU Make binary package to use with pkg_add at:
-ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/devel/gmake/README.html

+You need to use GUN Make instead of NetBSD's make.
 Remember to type gmake instead of make to compile LCDproc.

+The server will probably only compile on NetBSD/i386.

 Bus error (core dumped)
-It is likely that you did not have the right permission to access the ports.

-(not tested yet)
+It will compile fine on i386.

+If the build process fails, but you do know how to link a loadable
+module by hand, you can add the appropriate flags etcetera into
+acinclude.m4. Experience required. Please let us know if you got it

+dnl This macro checks to see if sys/sem.h defines union semun. Some
+dnl systems do, some systems don't. Your code must be able to deal with
+dnl this possibility; if HAVE_STRUCT_SEMUM isn't defined for a given system,
+dnl you have to define this structure before you can call functions
+dnl like semctl().
+dnl You should call ETR_SYSV_IPC before this macro, to separate the check
+dnl for System V IPC headers from the check for struct semun.

-
-/********************************************************************
-  How to make a driver for LCDproc
-
-  Note: Insert the name of your driver in place of the phrase "new_driver".
-  
-  1. Copy drv_base.c and drv_base.h to new_driver.c and new_driver.h.
-
-  2. Decide which functions you want to override, which ones you want
-     to leave alone, and which ones you don't want at all.  If you
-     write your own driver functions, they will get called when
-     appropriate.  Or, you can let the default driver "drv_base"
-     handle a function for you.  But, if you really don't want a
-     function, you can completely prevent your driver from providing
-     it.  This is discussed in step 5.
-  
-  2.1. Remove all functions which you don't want to override, and the
-     ones you don't want at all.
-
-  3. Rename all functions from "drv_base_*" to "new_driver_*".
-
-  4. Write the new driver functions.
-     Be sure to do one of the following in/for your new_driver_close():
-	- free the framebuffer lcd.framebuf
-	- let the default driver handle close()
-	- call drv_base_close()
-     This will ensure that the frame buffer gets freed.
-
-  5. Register your functions in your new_driver_init(), like the following:
-       driver->clear = new_driver_clear;    // We want to handle this one
-       driver->string = (void *)-1;         // Leave this to the default
-       driver->getkey = NULL;               // This should never get called
-
-     The convention here is to set NULL for all the functions which
-     your driver doesn't handle (and which you don't want the default
-     functions to be called for).  Or, set -1 to indicate that the
-     driver should support the function but can use the default
-     behavior in drv_base.c.  Or, to indicate that your driver should
-     handle a function, just set it like clear() above.
-       
-  6. Add the driver to lcd.c, in the physical drivers section, protected
-     by an #ifdef like the rest of the drivers are.
-
-  7. Add your driver to the Makefile, and Makefile.config, in the same
-     style as the existing ones.
-
-  Notes:
-
-  Don't call lcd.whatever() functions within your driver.  This causes
-  a lot of potentially puzzling problems.
-
-  However, feel free to access lcd.framebuf in your driver (but not in
-  your init() function!).  It will always point to the frame buffer
-  you should be writing to.  This will usually be your own frame
-  buffer, but could potentially be another frame buffer, if another
-  driver wants to access your functions.
-
-  Your driver will be provided with a frame buffer which contains one
-  byte per character on the LCD.  The default is a 20x4, so that's 80
-  bytes.  You can free this and reallocate it to something else if you
-  need to.  A graphical driver may want to do this, for example.
-
-  If you don't set a function pointer, it will default to NULL, since
-  they get nullified before the driver's init() is called.
-
-  Assume that your driver may be added or removed dynamically, and
-  that more than one instance may exist at a time.  In other words, it
-  should init and close cleanly, and not depend on global variables.
-
-  Special arguments will be passed through the "args" variable to your
-  _init() function.  This is just a string, and you determine the
-  syntax of it.  Please document the syntax so that it can easily be
-  included in the lcdproc config file.  I suggest arguments such as
-  "port=0x378" or "-device /dev/ttyS0".  These come directly from the
-  lcdproc server config file, so they should be human-readable.  An
-  example may look like this:
-
-    # Set up two MtxOrb LCD's and a curses display on VT 2
-    Driver MtxOrb -device /dev/ttyS0 -keypad on
-    Driver curses -color off -size 20x4 -vt 2
-    Driver MtxOrb -device /dev/ttyS3 -size 20x2 -keypad off
-    # Before you ask, no, not all of these options are implemented yet.
-
-  Also, the driver API (if it can be called that) may change soon.
-  There seem to be several functions which just don't do anything
-  important...  and there are other potential improvements too.
-
-  And...  When in doubt, look at how the other drivers do it.  :)
