Date: July 30, 2013 8:36:01 AM CEST
Bruno Le Floch submitted the unravel package. Version number: 0.0a License type: lppl Summary description: Watching TeX digest tokens Announcement text:
This package emulates large parts of TeX's behaviour when it chews on tokens, expanding and performing typesetting commands. Using unravel will let you go one step at a time through some complicated LaTeX code that you are trying to debug. It understands a whole breadth of TeX's features, from deeply nested expansion to box assignments, to characters, and the proper insertion of \everypar. The unravel package requires up-to-date "l3kernel" and "l3experimental" bundles, as well as the new package "gtl".
This package is located at http://mirror.ctan.org/macros/latex/contrib/unravel More information _will be_ at http://www.ctan.org/pkg/unravel ... but only after mid-August, because of the holiday period ... 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 Rübe-Pugliese

## unravel – Watching TeX digest tokens

The aim of this package is to help debug complicated macros. This is done by letting the user step through the execution of some code, going through the details of nested expansions, performing assignments, as well as some simple typesetting commands. To use this package, one should normally run in a terminal.

The unravel package requires up-to-date versions of the l3kernel, l3packages and l3experimental bundles.
