Description John Harlan 2016-01-22 08:13:23 UTC 
equery u output for gnupg states that the smartcard use flag is restricted to package versions less than 2.0.17-r1; while in fact the smartcard use flag is observed by version 2.0.28 and required for smartcard support.

Because I observed the misleading equery output and did not set the smartcard use flag (since it states it will be ignored), I wasteed ~15 hrs troubleshooting problems w/ my smartcard and GnuPG and even filed a bug report wasting valuable dev time (sorry about that!).

Please update the metadata.xml file such that equery output will more accurately reflect current use flag uses and restrictions.

Thank you.

Reproducible: Always

Steps to Reproduce:
1. Execute 'equery u app-crypt/gnupg'
2. Read output for smartcard and USB useflags
3. Execute 'USE="smartcard" emerge -p ">=app-crypt/gnupg-2.0.17-r1"'
4. Notice how the use flag is observed, even though equery says it's not allowed for the version selected for emerge.

I have tested this on a VM booting the latest Gentoo Live DVD (livedvd-amd64-multilib-20140826.iso) to confirm that the problem is not unique to my system.
