If Logtalk were an ECLiPSe library module it could contain a directive
:- export initialization(load_settings_file).
When a user imports/use_module/libs this module, load_settings_file/0
gets executed in the original current directory, which is what you want.

But I think you can't use this trick because logtalk is not a module.
Please don't use :- local initialization() instead - it currently
works as above (as long as the file isn't pre-compiled), but I'd
consider this a bug, so don't rely on it please.

I suppose we could introduce a global setting analogous to get_flag(cwd,D)
that returns the startup directory.  But, as Kish said, you can start
eclipse (via script or shortcut) with a -e option to save the startup
directory yourself:   eclipse -e "getcwd(D),setval(startup_cwd,D),..."
