version 0.12

This work is released under the LPPL v1.3c or later.

The metalogo package exposes the spacing parameters for the various TeX logos to
the end user. It is intended to help XeLaTeX users, who use various typefaces,
to easily optimise the logos for each typeface. Still, the package remains
useful if any typeface is used, not necessarily loaded through \XeTeX.
