 // At the time of this writing:
 //   * Windows and Mac builds ship with their own copy of NSS (3.15+)
 //   * Linux builds use the system's libnss, which is 3.14 on Debian (but 3.15+
 //     on other distros).
 //
 // Since NSS provides AES-GCM support starting in version 3.15, it may be
 // unavailable for Linux Chrome users.
 //
 //  * !defined(CKM_AES_GCM)
 //
 //      This means that at build time, the NSS header pkcs11t.h is older than
 //      3.15. However at runtime support may be present.
 //
 // TODO(eroman): Simplify this once 3.15+ is required by Linux builds.
