"""
|
|
The :mod:`cvsbible` modules provides a facility to import bibles from a set of CSV files.
|
|
|
|
The module expects two mandatory files containing the books and the verses.
|
|
|
|
The format of the books file is:
|
|
|
|
<book_id>,<testament_id>,<book_name>,<book_abbreviation>
|
|
|
|
For example
|
|
|
|
1,1,Genesis,Gen
|
|
2,1,Exodus,Exod
|
|
...
|
|
40,2,Matthew,Matt
|
|
|
|
There are two acceptable formats of the verses file. They are:
|
|
|
|
<book_id>,<chapter_number>,<verse_number>,<verse_text>
|
|
or
|
|
<book_name>,<chapter_number>,<verse_number>,<verse_text>
|
|
|
|
For example:
|
|
|
|
1,1,1,"In the beginning God created the heaven and the earth."
|
|
or
|
|
"Genesis",1,2,"And the earth was without form, and void; and...."
|
|
|
|
All CSV files are expected to use a comma (',') as the delimiter and double quotes ('"') as the quote symbol.
