main() is a function, and it has no special meaning in python - for gcmd
it serves as an entry point for every python plugin (so for gcmd main()
is predefined). When gcmd launches pyplugin, in fact it calls main()
function in it. The parameters have predefined (for gcmd) names and
contain values passed from gcmd:

        main_wnd_xid    XID of GNOME Commander main toplevel window
        active_cwd      full path of current dir of active pane
        inactive_cwd    full path of current dir of inactive pane
        selected_files  list of selected file uris in active pane
        
You can see the values passed to pyplugin when starting gcmd in console
with -d=p parameter. Here goes my log for md5sum:

        [PP] Calling md5sum.main()
        [PP] Selected files: 2
        [PP] Main window XID: 56623336 (0x36000e8)
        [PP] Active directory:   /home/piotr/download/Szkocja
        [PP] Inactive directory: /home/piotr/devel/EAL
        [PP] Result of call md5sum.main(): 1
        
There is some information on python plugins at gcmd help file
(accessible with F1).


Hope it'll be of aby help,
Piotr
