You can browse MVMR sources on Github.
All e-books offered on MVMR are based on freely distributed Dharma books.
For the creation of the e-books, markdown files (they are provided too) were converted to EPUB using pandoc.
Metadata handling and EPUB to AZW3/MOBI (both of them for kindle devices) conversion were done using calibre.
AZW3 (kindle) files were further processed using Hyphenate This!
