--------------------------+--------------------------------
 Attached is a patch updating taglib to v. 1.9.1.  Also, project now
 appears to be hosted on github.io rather than github.com--updated
 master_sites.  'port lint --nitpick' didn't like a trailing space on one
 line so I made it happy too.  ;)
