A list of package names. Symbols in these packages that have a macro definition are not
fmakunbound
when the delivery process deletes macros from the image (when :keep-macros is
nil
). Note that if these symbols are not referenced, they may be shaken anyway. When
:
:keep-macros is
nil
, this keyword has no effect.
