 About
 
-  The original name of this program is "C++check".
-  The name was changed to "cppcheck".
+    The original name of this program is "C++check" but it was later changed to "cppcheck".
 
 
 Compiling
 
-  Any C++ compiler should work.
-
-  The Makefile works under Linux.
-  To make it work under Windows with DJGPP, change "g++" to "gxx".
-
-  To build cppcheck with qmake, run these commands:
-
-   Generate Makefile (use 'debug' instead of 'release' if doing developer build)
-   (If you are using Mac OS, you need to add "-spec macx-g++" to the command):
-     qmake -config release
-
-   Build command-line tool, GUI and autotests:
-     make
-
-   To build command-line tool only:
-     make sub-src 
-
-   To build and run autotests:
-     make check
-
+    Any C++ compiler should work.
+
+    To build the GUI, you need Qt. The command line tool doesn't have any dependencies.
+
+    There are multiple compilation choices:
+      * SCons - cross platform build tool
+      * CMake - cross platform build tool
+      * qmake - cross platform build tool - but only the GUI can be built
+      * Visual Studio - Windows
+      * gnu make (for experts)
+      * g++ (for experts)
+
+
+    Scons
+    =====
+        Scons is a multi platform build tool. Python is required to run it.
+            scons
+
+
+    CMake
+    =====
+        CMake is a multi platform build tool with no dependencies.
+            cmake .
+            make
+
+
+    qmake
+    =====
+        You can use the gui/gui.pro file to build the gui.
+            cd gui
+            qmake
+            make
+
+
+    Visual Studio
+    =============
+        Use the cppcheck.sln file.
+
+
+    gnu make (for experts)
+    ======================
+        A simple Makefile generator is available and you can use it like this:
+            g++ -o dmake tools/dmake.cpp lib/filelister.cpp
+            ./dmake
+
+        The generated Makefile may need to be edited to fit your needs.
+        If it doesn't work, unfortunately we can't help you.
+
+
+    g++ (for experts)
+    =================
+        If you just want to build Cppcheck then you can use this command:
+            g++ -o cppcheck -Ilib cli/*.cpp lib/*.cpp
+
+        If it doesn't work, unfortunately we can't help you.
