This package allows one to easily define helper macros to insert comments in a LaTeX document. A convenient syntax enables you to mark text additions (e.g., \phf{I'm adding this text}), an in-line comment (e.g., We're the best \phf[I'm not sure about this.]), and text removals (e.g., \phf*{remove me}). New colors are assigned automatically to each commenter by default, and the appearance of all comments is highly customizable.
