How do you spawn httrack ? Using some bash-style scripting ? Using
execve()-style command ? Or using the library ? The later lets you track
precisely the mirror state (actualy, you have the same information you have on
the GUI version, which is another library client)

If you just want to track the completion state, you can either track the
process life, and/or the hts-in_progress.lock lock file, which is created at
the begining of the mirror, and deleted at the end of the program.

Note that the libtest/example.c source file gives you a good start to make a
very simple main app. to control the engine.

The 3.41 library core rourines should be more clean, and (hopefully) "more"
thread-safe - the current beta version also has some improvements in the API
(to catch some events)
