The cygwin-doc source files are kept in CVS. Please see https://cygwin.com/cvs.html for more information. BUILD REQUIREMENTS: bash bzip2 coreutils cygwin dblatex docbook-xml45 docbook-xsl gzip make texinfo perl xmlto OTHER NOTES: You may use docbook2X to convert the DocBook files into info pages. I have not been able to get a working docbook2X installation on Cygwin, so currently I convert the files on a machine running GNU/Linux. A few handmade files (cygwin.texi, intro.3, etc.) are found in the cygwin-doc-x.y-z-src.tar.bz2 package. It also contains the utilities for building the cygwin-doc-x.y-z "binary" package--simply run each step in the cygwin-doc-x.y-z.sh script.
