["Cygwin htmldoc Maintainer" <Brian.Inglis@SystematicSW.ab.ca>]

The following package has been upgraded in the Cygwin distribution:

* htmldoc	1.9.16

HTMLDOC reads HTML and Markdown source files or web pages and generates
EPUB, HTML, PostScript, or PDF files with an optional table of contents.
HTMLDOC normally expects structured documents, with chapters, headings,
lists, tables, etc. but also handles web pages in HTML, Markdown, and
other continuous formats.
