+    HTTrack external callbacks example : changing the destination filename
+    Example of <wrappername>_init and <wrappername>_exit call (httrack >> 3.31)
+    .c file
+
+    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,string1,string2
