The REALSCRIPTS package
=======================
Small package to replace `\textsuperscript` & `\textsubscript`
by equivalent commands that use OpenType font features
to access the appropriate glyphs if possible.
Provides `\textsubsuperscript` (and `\textsupersubscript`) for
setting subscripts and superscripts on top of each other.
Also patches LaTeX's default footnote command to use this
new `\textsuperscript` for footnote symbols.
Requires fontspec running on either XeLaTeX or LuaLaTeX.
For more information see the documentation realscripts.pdf.
Change History
--------------
v0.3c 2013/03/18
* Fix completely broken `\textsupersubscript`.
* Allow `\textsubsuperscript` at the start of a paragraph (!).
* Sync with expl3 updates.
v0.3b 2013/02/27
* Remove internal definition of two functions that have since been defined
in expl3 (`\dim_min:nn` and `\dim_max:nn`).
v0.3 2010/09/30
* New commands `\textsubsuperscript` and `\textsupersubscript` added.
* Fix an "infinite loop" bug added in the last version, triggered
when loading the `xltxtra` package with the `[no-sscript]` option.
v0.2 2010/09/20
* Add feature to specify the font of the patched footnotemark.
This behaves well with KOMA-Script's `\setkomafont`, as well.
v0.1
* First release
* Extracted from the xltxtra package
