An important feature of star (when called "star") is that is does not extract
files from the archive if they are not newer than the file on disk.
Together with an interactive mode and the ability to specify many patterns,
this allows to reduce the number of manual interactions with in the interactive
mode.
Together with the built in find command this help a lot to minimize the amount
of typingto get a file back (thing e.g. on usinf the find syntax to specify a
time (file age) range for files.

People who know find(1) by heart and who did understand where/how the libfind
code is used inside star will be able to use the built in find to make life
easier. Well, find(1) uses not a really simple language but once you did
understand it, you are able to do even compley things easily.
