 # $FreeBSD$
 #
 # This include file <doc.project.mk> is the FreeBSD Documentation Project
 # co-ordination make file.
 #
 # This file includes the other makefiles, which contain enough
 # knowledge to perform their duties without the system make files.
 #
 
 # ------------------------------------------------------------------------
 #
 # Document-specific variables:
 #
 #	DOC		This _must_ be set if there is a document to
 #			build.  It should be without prefix.
 #
 #	DOCFORMAT	Format of the document.  Defaults to docbook.
 #			docbook is also the only option currently.
 #
 # 	MAINTAINER	This denotes who is responsible for maintaining
 # 			this section of the project.  If unset, set to
 # 			doc@FreeBSD.org
 #
 
 # ------------------------------------------------------------------------
 #
 # User-modifiable variables:
 #
 #	PREFIX		Standard path to document-building applications
 #			installed to serve the documentation build
 #			process, usually by installing the docproj port
 #			or package.  Default is ${LOCALBASE} or /usr/local
 #
 #	NOINCLUDEMK	Whether to include the standard BSD make files,
 #			or just to emulate them poorly.  Set this if you
 #			aren't on FreeBSD, or a compatible sibling.  By
 #			default is not set.
 #
 
 # ------------------------------------------------------------------------
 #
 # Make files included:
 #
 #	doc.install.mk	Installation specific information, including
 #			ownership and permissions.
 #
 #	doc.subdir.mk	Subdirectory related configuration, including
 #			handling "obj" builds.
 #
 # 	doc.common.mk	targets and variables commonly used in doc/ and
 #			www/ tree.
 #
 # DOCFORMAT-specific make files, like:
 #
 #	doc.docbook.mk	Building and installing docbook documentation.
 #			Currently the only method.
