-This directory contains the visual studio project files used to generate the precompiled binaries for gmp and mpfr.
+This README contains instructions to create compiled binaries for gmp and mpfr for Visual Studio
+with the names expected by the auto-linking feature of CGAL (as those provided with the
+Windows Installer)
 
-To install it:
+STEP 1.
 
-1.Download gmp-4.2.2 and mpfr-2.3.1 from 
+  Download the Brian Gladman's ports for gmp and mpfr for Visual Studio from:
 
-2.Download the Gladman's ports to Visual Studio from
+    http://fp.gladman.plus.com/computing/gmp4win.htm
 
-http://fp.gladman.plus.com/computing/gmp4win.htm
+  You would choose a version of gmp and mpfr according to the ports available.
+  
+STEP 2.
 
-and follow the instructions to properly unzip the archive, but do not build any libraries.
+  Download the correspoding versions of gmp and mpfr depending on the Gladman's port downloaded
+  
+SETP 3.
 
-3.Unzip "mangled_gmp_VC.zip" at the root directory of your gmp-4.2.2 installation.
-4.Unzip "mangled_mpfr_VC.zip" at the rot directory of your mpfr-2.3.1 installation.
+  Follow the instructions supplied by Gladman's port and build one of the static versions
+  of the gmp and mpfr libs.
+    
+  Typically, in this step you would
+  
+     untar the gmp, mpfr and ports archives under a common root folder
+     launch gmp.sln
+     build the preliminary "gen_*" targets 
+     build one of the static library targets, such as "gmp_lib_gc"
+     launch mpfr.sln
+     renamed "mparam_h.in" to "mparam.h" 
+     build the target lib_mpfr.
+  
+  but the details may vary depending on the port downloaded. Make sure to follow
+  the port instructions and build ONE static version of gmp and mpfr. You can choose
+  the generic version (_gc) or one of the optimized (_pN) version but make sure to build only one.
+  
+  You would end up with a structure similar to the following:
+    
+        <base directory>
+          gmp-4.2.4
+            build.vc9
+              lib_gmp_gc
+                Win32
+                  Debug
+                    gmp.lib
+                    gmp.pdb
+                  Release
+                    gmp.lib
+                    gmp.pdb
+          mpfr-2.3.2
+            buid.vc9 
+              lib_mpfr
+                Win32
+                  Debug
+                    mpfr.lib
+                    mpfr.pdb
+                  Release
+                    mpfr.lib
+                    mpfr.pdb
 
-5.To build the gmp libraries open <gmp-4.2.2 root>/build.vc<8|9>/lib_gmp_gc/mangled_lib_gmp_gc.vcproj in Visual Studio and build it.
 
-6.TO build the mpfr libs, *after* having built gmp, use <mpfr-2.3.1 root>/build.vc<8|9>/lib_mpfr/mangled_lib_mpfr.vcproj

+  copy the batch script "create_mangled_versions.bat" into the base directory
+  containing gmp and mpfr.
+  
+  Run it passing the directory containing gmp then mpfr. For example:
+  
+    C:\>create_mangled_versions gmp-4.2.4
+    C:\>create_mangled_versions mpfr-2.3.2
+    
+  This script scans the given directory in search for gmp and mpfr binaries.
+  Each time one is found, it creates a copy of it using a "mangled" named that
+  conforms to the autolinking requirements. It constructs the mangled based based
+  on the relative downpath to the library found. For example, if it finds
+    
+    build.vc9\lib_gmp_gc\Win32\Debug\gmp.lib
+    
+  it creates a copy, in the same directory, named:
+  
+    gmp_vc90_mt_gd.lib
+    
+  All mangled binaries are also copied to a folder named "mangled_binaries" that
+  the script creates in the directory where it is run.
