This keyword takes a list of packages to be retained. All packages in the list are kept in the delivered image, regardless of the values of the :smash-packages and :delete-packages keywords.
If
:packages-to-keep
is
:all
, then the two variables above are set to
nil
. See also Coping with intern and find-symbol at runtime.
Note:
Other keywords push packages onto the
:packages-to-keep
list.
Note:
When you keep a package by
:packages-to-keep
, this does not cause that package's symbols to be kept. To retain symbols, see Ensuring that symbols are kept.
