Name of contribution: perfectcut Author's name: Guillaume Munch-Maccagnoni Package version: 1.9 Location on CTAN: macros/latex/contrib/perfectcut Summary description: Brackets whose size adjusts to the nesting License type: lppl

Announcement text given by the package's contributor:

This package defines the command perfectcut#1#2 which displays a bracket <#1||#2>. Its effect is to determine the size of the bracket depending on the number of nested perfectcut (regardless of the contents). It is intended for use:

• In proof theory, for term notations of sequent calculus,
• In computer science, for the modeling of abstract machines.

This package also offers a reimplementation of ig, igg, etc. into arbitrary-size variants.
