+/* ------------------------------------------------------------
+ * Primitive type fragments and macros 
+ * ------------------------------------------------------------ */
+
+/*
+  This file provide fragments and macros for the C/C++ primitive types. 
+
+  The file defines default fragments for the following types:
+
+    bool
+    signed char
+    unsigned char
+    signed wchar_t     // in C++
+    unsigned wchar_t   // in C++
+    short
+    unsigned short
+    int
+    unsigned int
+    float
+    size_t
+    ptrdiff_t
+
+  which can always be redefined in the swig target language if needed.
+  
+  The fragments for the following types, however, need to be defined
+  in the target language always:
+
+    long
+    unsigned long
+    long long
+    unsigned long long
+    double
+ 
+  If they are not provided, an #error directive will appear in the
+  wrapped code.
+
+  --------------------------------------------------------------------
+  
+  This file provides the macro
+
+    %typemaps_primitive(CheckCode, Type)
+
+  which generate the typemaps for a primitive type with a given
+  checkcode. It is assumed that the primitive type is 'normalized' and
+  the corresponding SWIG_AsVal(Type) and SWIG_From(Type) methods are
+  provided via fragments.
+  
+   
+  The following auxiliary macros (explained with bash pseudo code) are
+  also defined:
+
+    %apply_ctypes(Macro)
+      for i in C Type
+      do
+        Macro($i)
+      done
+
+    %apply_cpptypes(Macro)
+      for i in C++ Type
+      do
+        Macro($i)
+      done
+
+    %apply_ctypes_2(Macro2)
+       for i in C Type
+       do
+         for j in C Type
+         do
+            Macro_2($i, $j)
+         done
+       done
+
+    %apply_cpptypes_2(Macro2)
+       for i in C++ Type
+       do
+         for j in C++ Type
+         do
+            Macro_2($i, $j)
+         done
+       done
+
+    %apply_checkctypes(Macro2)
+       for i in Check Type
+       do
+         Macro2(%checkcode($i), $i)
+       done
