This small package replaces \textsuperscript and \textsubscript commands by equivalent commands that use OpenType font features to access appropriate glyphs if possible. The package also patches LaTeX's default footnote command to use this new \textsuperscript for footnote symbols. The package requires fontspec running on either XeLaTeX or LuaLaTeX. The package holds functions that were once parts of the xltxtra package, which now loads realscripts by default.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
