SchoolTool is a technology to manage calendars, gradebooks, attendance, reporting, and more. It can be deployed to small teams or to entire institutions .
I hadn't planned on tackling this one yet, as I have a growing queue, but took a minute to survey what's involved and found myself committed before I knew it.
Attached is the patch I developed from build notes. I will follow up with build notes for the prototype.
I'll note here something that may be a problem: PDF functionality for reporting depends on msttcorefonts from Multiverse. Documentation suggests an alternative is being pursued, but no mention of progress is made.
