* genome-euro/asia. For proper testing of session loading on hgSession and
* hgLogin, configure your sandbox to use genome.ucsc.edu as a "remote login"
* (wiki.host=genome.ucsc.edu). Make sure that links to load sessions go to
* your sandbox, but login links go to genome.ucsc.edu. For QA, tell them to
