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 .
