+THE XLTXTRA PACKAGE 2018/12/31 v0.7
+===================================
+
+This package was previously used to provide a number of small
+features that are useful for XeLaTeX. As of fontspec v2, many
+of these have now been incorporated into that package. More
+recently, other updates to LaTeX2e itself have eliminated some
+of the workarounds previously included in this package.
+
+This package therefore no longer does as much as it used to,
+but is still provided for backwards compatibility. A summary:
+
+- Loads fontspec.
+
+- Loads Andrew Moschou's metalogo package for customised
+  `\XeTeX` and `\XeLaTeX` logos.
+
+- Loads the realscripts package to obtain OpenType-feature
+  subscript and superscript glyphs in `\textsuperscript` etc.,
+  including in footnotes.
+
+- `\showhyphens` is redefined so it now works.
+
+- Defines the dubiously useful commands:
+  - `\vfrac` - for vulgar fractions using OpenType features
+  - `\namedglyph` - to access font glyphs by name
+
+For more information see the documentation xltxtra.pdf.
+
+
