Bible Organisational System (an internationalised Python library for handling different book/chapter/verse materials like Bibles and commentaries)
Many things work for many Bibles. Tested on hundreds of USFM and other Bibles, as well as quite a few different import formats. Still doesn't handle all USFM 3 fields. Still need to redesign the internal Bible format to handle complex nesting, etc. Works with Biblelator v0.44.
