This is the MacPorts documentation directory. To generate it you have to checkout the whole "trunk/doc-new" directory and you need the "docbook-xsl", "docbook-xml" and "libxslt" ports. If your port installation isn't in /opt/local look at "Makefile" how you have to change this setup. To generate the guide and the man pages just use "make" in this directory. Then they are generated in guide/html and man/man.
