The first non-option argument, is the menu entry to start from; it is searched for in all 'dir' files along INFOPATH.
If it is not present, info merges all 'dir' files and shows the result.
Remaining arguments are treated as the names of menu items relative to the initial node visited. For a summary of key bindings, type H within Info.
