This package offers a collection of macros to help in the process of writing a paper. You may add comments, todo notes, etc. during revision, in a colourful way. The package also summarizes the inserted notes at the end of the document. There are some predefined note commands as well as a way of defining new ones to suit the user’s needs. You may safely remove this package once the paper is finished. This package depends on the following other LaTeX packages: kvoptions, manfnt, marginnote, tikzpagenodes, xcolor, and, optionally, microtype. Note: “zebra” is the name of the package author’s lab.
