# 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.
