Collection of chants following the 1983 Ordo cantus officii.

(Yes, I do know that there is already a new 2015 edition of the OCO.)

Install gregorio (version 4.x is required) and LuaLaTeX.

Get some Ruby interpreter and install gems gly and rake.

gem install gly rake

Then run rake tasks. rake alone builds all possible targets.

See output of rake -T for available targets. E.g. rake libelli:psalterium builds a book containing all already transcribed chants of the psalter.

(If the build crashes, don't hesitate to punch me. I always use the latest development version of gly for work on this project and I am quite reluctant releasing new gly versions, so the last released gly isn't always capable of building this project.)

Contributions are most welcome.

• transcribe scores from the printed sources designated by OCO (e.g. antiphons for some feast)
• proofread some part of the existing transcriptions
• transcribe some of the unedited antiphons
• criticize and improve existing transcriptions of unedited antiphons
