+# Minimal makefile for Sphinx documentation
 #
-# SPDX-License-Identifier: CC-BY-2.0-UK
-#
-# This is a single Makefile to handle all generated Yocto Project documents,
-# which includes the BitBake User Manual and the Toaster User Manual.
-# The Makefile needs to live in the documents directory and all figures used
-# in any manuals must be .PNG files and live in the individual book's figures
-# directory as well as in the figures directory for the mega-manual.
-#
-# Note that the figures for the Yocto Project Development Tasks Manual
-# differ depending on the BRANCH being built.
-#
-# The Makefile has these targets:
-#    all:       If you leave off the target then "all" is implied.
-#               You will generate HTML and a tarball of files.
-#
-#    pdf:	generates a PDF version of a manual.  Not valid for the
-#		Quick Start or the mega-manual (single, large HTML file
-#		comprised of all Yocto Project manuals).
-#    html:	generates an HTML version of a manual.
-#    tarball:	creates a tarball for the doc files.
-#    validate:	validates
-#    publish:	pushes generated files to the Yocto Project website
-#    clean:	removes files
-#
-# The Makefile can generate an HTML and PDF version of every document except the
-# Yocto Project Quick Start and the single, HTML mega-manual, which is comprised
-# of all the individual Yocto Project manuals.  You can generate these two manuals
-# in HTML form only.  The variable DOC indicates the folder name for a given manual.
-# The variable VER represents the distro version of the Yocto Release for which the
-# manuals are being generated.  The variable BRANCH is used to indicate the
-# branch (edison or denzil) and is used only when DOC=dev-manual or
-# DOC=mega-manual.  If you do not specify a BRANCH, the default branch used
-# will be for the latest Yocto Project release.  If you build for either
-# edison or denzil, you must use BRANCH. You do not need to use BRANCH for
-# any release beyond denzil.
-#
-# To build a manual, you must invoke Makefile with the DOC argument.  If you
-# are going to publish the manual, then you must invoke Makefile with both the
-# DOC and the VER argument.  Furthermore, if you are building or publishing
-# the edison or denzil versions of the Yocto Project Development Tasks Manual or
-# the mega-manual, you must also use the BRANCH argument.
-#
-# Examples:
-#
-#     make DOC=bsp-guide
-#     make html DOC=brief-yoctoprojectqs
-#     make pdf DOC=ref-manual
-#     make DOC=dev-manual BRANCH=edison
-#     make DOC=mega-manual BRANCH=denzil
-#
-# The first example generates the HTML version of the BSP Guide.
-# The second example generates the HTML version only of the Quick Start.  Note
-# that the Quick Start only has an HTML version available.  So, the
-# 'make DOC=brief-yoctoprojectqs' command would be equivalent. The third example
-# generates just the PDF version of the Yocto Project Reference Manual.
-# The fourth example generates the HTML 'edison' version of the YP Development
-# Tasks Manual.  The last example
-# generates the HTML version of the mega-manual and uses the 'denzil'
-# branch when choosing figures for the tarball of figures.  Any example that does
-# not use the BRANCH argument builds the current version of the manual set.
-#
-# The publish target pushes the generated manuals to the Yocto Project
-# website.  Unless you are a developer on the YP team, you will not succeed in
-# pushing manuals to this server.  All files needed for the manual's HTML form are
-# pushed.
-#
-# Examples:
-#
-#    make publish DOC=bsp-guide VER=1.7
-#    make publish DOC=adt-manual VER=1.6
-#    make publish DOC=dev-manual VER=1.1.1 BRANCH=edison
-#    make publish DOC=dev-manual VER=1.2 BRANCH=denzil
-#
-# The first example publishes the 1.7 version of both the PDF and HTML versions of
-# the BSP Guide.  The second example publishes the 1.6 version of both the PDF and
-# HTML versions of the ADT Manual. The third example publishes the 1.1.1 version of
-# the PDF and HTML YP Development Tasks Manual for the 'edison' branch.  The fourth
-# example publishes the 1.2 version of the PDF and HTML YP Development Tasks Manual
-# for the 'denzil' branch.
-#
-# IN MEMORIAM: This comment is to remember Scott Rifenbark (scottrif), whom we lost
-# in January, 2020. Scott was the primary technical writer for the Yocto Project for
-# over 9 years. In that time, he contributed many thousands of patches, built this
-# documentation tree, and enabled tens of thousands of developers to succeed with
-# embedded Linux. He ran this Makefile many thousands of times. Godspeed, Dude.
