package.
Version number: 1.0
License type: lppl1.3
Summary description: Typeset formal proofs in the style of
sequent calculus.
Announcement text:

First public release: This package provides commands to typeset proof trees in the style of sequent calculus and related systems. The commands allow for writing inferences with any number of premisses and alignment of successive formulas on an arbitrary point. Various options allow complete control over spacing, styles of inference rules, placement of labels, etc. The package requires pgfkeys from the PGF/TikZ bundle for the option system.

This package is located at http://mirror.ctan.org/macros/latex/contrib/ebproof/ More information is at http://www.ctan.org/pkg/ebproof We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .

Thanks for the upload. For the CTAN Team Petra RĂ¼be-Pugliese
