= D =
Said of a program or feature that is
considered obsolescent and in the process of being phased out,
usually in favor of a specified replacement. Deprecated features
can, unfortunately, linger on for many years. This term appears
with distressing frequency in standards documents when the
committees writing the documents realize that large amounts of
extant (and presumably happily working) code depend on the
feature(s) that have passed out of favor. See also dusty deck.
[Usage note: don't confuse this word with `depreciate', or the verb form
`deprecate' with `depreciated`. They are different words; see any
dictionary for discussion.]
