I know there are six million ways to Sunday to get this done, but I'm kind of pleased that I've cobbled together a podcast-posting script that takes my Auphonic output files and:

•Renames and uploads .mp3 to blubrry
•Uploads .vtt transcript and .json chapters to an online location accessible to blubrry
•Extracts my mp3 tag comments and creates draft WordPress post
•Uploads .mp4 version of podcast to YouTube and attached .srt transcript (using previously extracted comments as description)
