How do I view the contents of a Mac OS X Detached Code Signature?

I spent some time cleaning up my TCC data. During that I learned that some TCC info is cached in “Mac OS X Detached Code Signature” files. Is there a way to dump their contents suitable for human consumption? The codesign tool doesn’t seem to do it (or I can’t figure out how to invoke it).
