Fixes [YOCTO #5035] By default, the DL_DIR does not get files from Git repositories that are suitable for mirroring. There is a work-around by using the BB_GENERATE_MIRROR_TARBALLS variable, which, when set, causes the build system to generate tarballs for the Git repositories and place them in the DL_DIR. To address this, I added a new variable description for the BB_GENERATE_MIRROR_TARBALLS varible, updated the DL_DIR variable to indicate that "out-of-the-box" the YP puts suitable mirror files into the DL_DIR for everthing except Git repositories. Some other sections were updated where discussion revolved around pulling down source files. The QS had a spot where the BB_GENERATE_MIRROR_TARBALLS variable was actually used in an example. And, the expanded discussion on the BitBake process had a couple spots that deserved a mention.

documentation
This is the directory that contains the Yocto Project documentation. The Yocto Project source repositories at http://git.yoctoproject.org/cgit.cgi have two instances of the "documentation" directory. You should understand each of these instances.
poky/documentation - The directory within the poky Git repository containing the set of Yocto Project manuals. When you clone the poky Git repository, the documentation directory contains the manuals. The state of the manuals in this directory is guaranteed to reflect the latest Yocto Project release. The manuals at the tip of this directory will also likely contain most manual development changes.
yocto-docs/documentation - The Git repository for the Yocto Project manuals. This repository is where manual development occurs. If you plan on contributing back to the Yocto Project documentation, you should set up a local Git repository based on this upstream repository as follows:
git clone git://git.yoctoproject.org/yocto-docs
Changes and patches are first pushed to the
yocto-docs Git repository. Later, they make it
into the poky Git repository found at
git://git.yoctoproject.org/poky.
Manual Organization
Folders exist for individual manuals as follows:
- adt-manual - The Yocto Project Application Developer's Guide.
- bsp-guide - The Yocto Project Board Support Package (BSP) Developer's Guide
- dev-manual - The Yocto Project Development Manual
- kernel-dev - The Yocto Project Linux Kernel Development Manual
- ref-manual - The Yocto Project Reference Manual
- yocto-project-qs - The Yocto Project Quick Start
- mega-manual - An aggregated manual comprised of all YP manuals and guides
- profile-manual - The Yocto Project Profile and Tracing Manual
Each folder is self-contained regarding content and figures. Note that there is a sed file needed to process the links of the mega-manual. The sed file is located in the tools directory. Also note that the figures folder in the mega-manual directory contains duplicates of all the figures in the YP folders directories for all YP manuals and guides.
If you want to find HTML versions of the Yocto Project manuals on the web, go to http://www.yoctoproject.org and click on the "Documentation" tab. From there you have access to archived documentation from previous releases, current documentation for the latest release, and "Docs in Progress" for the release currently being developed.
In general, the Yocto Project site (http://www.yoctoproject.org) is a great reference for both information and downloads.
Makefile
The Makefile processes manual directories to create HTML, PDF, tarballs, etc. Details on how the Makefile work are documented inside the Makefile. See that file for more information.
To build a manual, you run the make command and pass it the name of the folder containing the manual's contents. For example, the following command run from the documentation directory creates an HTML and a PDF version of the ADT manual. The DOC variable specifies the manual you are making:
$ make DOC=adt-manual
poky.ent
This file defines variables used for documentation production. The variables are used to define release pathnames, URLs for the published manuals, etc.
template
Contains various templates, fonts, and some old PNG files.
tools
Contains a tool to convert the DocBook files to PDF format. This folder also contains the mega-manual.sed file, which is used by Makefile to process cross-references from within the manual that normally go to an external manual.
