Maarten Fokkinga submitted the calculation

package. Version number: 1.0 License type: lppl1.3 Summary description: Typesetting reasoned calculations, also called calculational proofs. Announcement text: ---------------------------------------------------------------------- The "calculation" environment formats reasoned calculations, also called calculational proofs. The notion of reasoned calculations or calculational proofs was originally advocated by Wim Feijen and Edsger Dijkstra. The "calculation" package accepts options "fleqn" and "leqno" (with the same effect as LaTeX options "fleqn" and "leqno", and inherits these from the document class), it allows steps and expressions to be numbered (by LaTeX equation numbers, obeying the LaTeX "\label" command to refer to these numbers), and a step doesn't take vertical space if its hint is empty. An expression in a calculation can be given a comment; it is placed at the side opposite to the equation numbers. Calculations are allowed inside hints although numbering and commenting is then disabled. ---------------------------------------------------------------------- This package is located at http://mirror.ctan.org/macros/latex/contrib/calculation More information is at http://www.ctan.org/pkg/calculation We are supported by the TeX Users Group http://www.tug.org .
