how do I grok appcast?
cask docs say brew can parse appcasts in sparkle, hockeyapp, devmate, sourceforge, and plain old HTML:
- github (atom)
- sparkle (XML)
- hockeyapp (sparkle)
- devmate (sparkle)
- sourceforge (RSS)
what does brew cask do with HTML appcasts? nothing? the URL is for human eyes only?
I could clone the brew source, and flail about with find/exec/grep but this must be documented somewhere surely
