Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank

A steady, soothing progression of colors met and swirled on the ceiling. There were one hundred couches in the large room, neatly spaced in rows of ten. Five Jaunt attendants circulate, speakingin low, cherry voices and offering glasses of milk. At one side of the room was the entranceway, flanked by armed guar
