Hi Dale .. extended attributes are basically key/value pairs, all the xattr code does
 currently is a simple regex match against the names of any extended attributes
that may be present for the file.
Capabilities are also stored as extended attributes so the '-cap' test is
specifically to perform a regex match against the value of the security.capability
 extended attribute if it's present.

My initial use case was to find files that had SUID/SGID capabilities set.

It actually didn't take long to write the PoC utilities but I'm happy to accept
any suggestions  ..
