Decided to do a slightly bigger proof of concept... this bcc_relay.ash file will, if made your masterRelayOverride, apply all of the bumcheekcity relay overrides. If you peek at it, you'll notice that he'd already made them all functions (except for inventory) so they translate to a master calling system very easily. Alternatively, the functions could be put into either a single "bcc_functions" file, or included in the master file. The advantage of keeping them outside the actual master file is that this makes it easier for people to splice their own sets of overrides together.
Another benefit of using a master override is that, if I wanted to, I could call many different functions on the same page, as long as they don't have conflicting names or do things that don't work together... In this case, I just took the full bcc set and put it together, but I could put anything else in there I wanted as well.
Also, your overrides don't actually have to follow the location name. If I wanted the bcc relays to be differentiated, I could rename them like bcc_beach, bcc_campground, bcc_town_altar, and it wouldn't affect whether or not they'd work, but if the user already had some custom relay scripts, it wouldn't necessarily disrupt their usage...
Anyways, to make this work, unzip the 0.3 version of BCC relays into the relay folder (backup if you already have others you want), put bcc_relay.ash in there, and set masterRelayOverride=bcc_relay.ash and... done.
