VERSE RIPPER  1.7
---------------------------
This will extract all the verses from a txt document into a nice list.
Verse formatting is assumed to be from BSF study questions.  
ref:  https://www.bsfinternational.org/

1. Copy-paste the study questions into a text file.
2. Execute at command line against the file like this:  "verserip questions.txt"
3. Copy-paste the list of verses into your verse retrieval application. 
You can then use this list for retrieval from your favorite application.
