Name of contribution: synproof Author's name: Paul Isambert Location on CTAN: /macros/latex/contrib/synproof Summary description: Easy drawing of syntactic proofs (a.k.a. derivations) in modern logic. License type: lppl

Announcement text: ---------------------------------------------------------------------- This is a set of macros based on PSTricks that will enable you to draw syntactic proofs easily (inspired by the Gamut books). Very few commands are needed, however fine tuning of the various parameters (dimensions) can still be achieved through key=value pairs. ----------------------------------------------------------------------
