When signing a bundle, specifies that nested code content such as helpers, frameworks, and plug-ins, should be recursively signed in turn. Beware that all signing

options you specify will apply, in turn, to such nested content.

When verifying a bundle, specifies that any nested code content will be recursively verified as to its full content. By default, verification of nested content is lim-

ited to a shallow investigation that may not detect changes to the nested code.

subject; anything nested indirectly will require recursive application of the codesign command.
