/*
    HTTrack library example
    .c file

    To Build on Windows:
    - install winhttrack
    - set the proper path in the project settings (especially for the httrack lib and dll)
    - compile in multithreaded DLL
    - avoid precompiled headers with VC

    To Build on Linux:
    - install httrack
    - link with libhttrack.so and compile using something like:
      gcc example.c -I/usr/include/httrack -lhttrack
