% April, 2020
% To avoid stepping on it, rename \alpha ↦ \coffeealpha.
% See https://bugs.debian.org/958346
% These macros are being renamed, for extra safety:
% \alpha ↦ \coffeealpha
% \angle ↦ \coffeeangle
% \bleed ↦ \coffeebleed
% \scale ↦ \coffeescale
% \variety ↦ \coffeevariety
% \xoff ↦ \coffeexoff
% \yoff ↦ \coffeeyoff
