% The tweaklist.sty package redefines the itemize, enumerate and description packages, so that all parameters can be adjusted.
% This was done by copying the original definitions, and adding "hook commands" that are executed when entering the environment.
% The hook commands are initially empty, but can be redefined with \renewcommand.
