If a cross-reference is to a single word, for example, a command name like this:
tar (19.5),
the cross reference is probably to an article that introduces that command.
Cross references to phrases, like this:
writes the verbose information to its standard output (19.8)
are to an article that explains more about the concept or problem
printed in gray.
Cross references don't necessarily give a complete list of all articles
about a topic.
We've tried to pick one or a few articles that give the best information.
For a more complete list, use the Index.
