     HTTrack external callbacks example : changing folder names ending with ".com"
     with ".c0m" as a workaround of IIS bug (see KB 275601)
 
-    How to use:
-    - compile this file as a module (callback.so or callback.dll)
-      example:
-      (with gcc)
-      gcc -O -g3 -Wall -D_REENTRANT -DINET6 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -shared -o callback.so callbacks-example-filename.c
-      or (with visual c++)
-      cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"callback.dll" callbacks-example-filename.c
-    - use the --wrapper option in httrack:
-      httrack --wrapper save-name=callback:mysavename
+    How to build: (callback.so or callback.dll)
+      With GNU-GCC:
+        gcc -O -g3 -Wall -D_REENTRANT -shared -o mycallback.so callbacks-example.c -lhttrack1
+      With MS-Visual C++:
+        cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"mycallback.dll" callbacks-example.c libhttrack1.lib
+
+      Note: the httrack library linker option is only necessary when using libhttrack's functions inside the callback
