Last change on this file since 28760 was 21758, checked in by kjdon, 14 years ago

now we dynamically generate srclink (and /srclink, and new srchref which is the link without the a tag), using srclink_file metadata. This is to get gs2 receptionist stuff out of metadata and into the source code where it belongs
