----------------------------------------------
+## How to use agl-devel in conditionnal builds
 
 The following example shows how to activate C/C++ code
 specific to agl-devel:
 
-	CPPFLAGS_append_agl-devel = " -DAGL_DEVEL"
+```yocto
+CPPFLAGS_append_agl-devel = " -DAGL_DEVEL"
+```
 
 Using this, any code enclosed in
 
-	#ifdef AGL_DEVEL
-	...my code specific to agl-devel...
-	#endif
+```yocto
+#ifdef AGL_DEVEL
+...my code specific to agl-devel...
+#endif
+```
 
 will normaly be effective only if agl-devel is set on.
 
 At this time, it is recommended to use AGL_DEVEL as tag
 within C/C++ code.
