Texinfo 7.0 released

[Gavin Smith]

We have released version 7.0 of Texinfo, the GNU documentation format.

This package contains tools to produce documentation in various
formats, including HTML and PDF, from source files in the Texinfo
format.  Texinfo is a text-based format with commands for marking text,
document structuring and indexing.
