If the examples given for launching an out-of-tree build are executed
as-is, this will result in the error message
Please configure Buildroot first (e.g. "make menuconfig")
Even if "make menuconfig" was run before, it's still not going to work
because the out-of-tree build doesn't use the in-tree .config.
Therefore, the example really should start with some config option.
Since "make menuconfig" is used in most other examples of creating a
config, use that here as well. Extend both examples with "menuconfig".

Back many years ago, we developed an Eclipse plugin that simplified
the usage of Buildroot toolchains. Enabling the BR2_ECLIPSE_REGISTER=y
was registering the Buildroot toolchain into a special file in your
HOME folder that the Eclipse plugin would recognize to allow to
directly use the Buildroot cross-compiler.
This Eclipse plugin has not been maintained for years. The last commit
in the repository dates back from September 2017. Since then Eclipse
has moved on, and the plugin is no longer compatible with current
versions of Eclipse.
Also, Eclipse is probably no longer that widely used in the embedded
Linux space, as other more modern IDEs have become more popular.
All in all, it's time to say good bye to this Eclipse integration.

Currently, the packages are sorted smallest first, and biggest last
(with unknown and others second-to-last and last, resp.).
Add an option to invert the ordering (but keeping unknown and others at
their current positions).
This has the nice side effect that we can now control the colours
assigned to the biggest package(s), as the colours are cycled from the
first to the last. Currently, the biggest packages gets a redish colour,
which is appropriate, but the second gets a greenish one, which is not
as appropriate (but changing that can come later).

When dealing with embedded devices, storage is more often than not some
kind of flash device, on which the memory is usually counted as powers
of 1024 instead of powers of 1000. As such, people may prefer reports
using IEC prefixes [0] instead of the SI prefixes.
Add an option to that effect.
We use argparse's ability to use custom actions [1] [2], to provide a
set of options that act on a boolean, but has a single help entry and
internally ensures consistency of the settings. We could have been using
the more conventional store_true/store_false actions instead, but that
would have meant either two help entries, one for each set of options,
and/or some logic after parse_args() to check the validity of the
settings.

Currently, we group packages that contribute less then 1%, into the
"Other" category.
However, in some cases, there can be a lot of very comparatively small
packages, and they may not exceed this limit, and so only the "Others"
category would be displayed, which is not nice.
Conversely, if there are a lot of packages, most of which only so
slightly exceeding this limit, then we get all of them in the graph,
which is not nice either.
Add a way for the developers to pass a different cut-off limit. As for
the dependency graph which has BR2_GRAPH_DEPS_OPTS, add the environment
variable BR2_GRAPH_SIZE_OPTS to carry those extra option (in preparation
for more to come, later).

The graph-depends was not very consistent in colors vs. colours: some

Let's settle on the US spelling, colors.
This change the user-visble option --colours to --colors, but it is
unlikely that a lot of users customize the colors through
BR2_GRAPH_DEPS_OPTS, so this user interface change is considered

We currently have two places where we recommend where BR2_DL_DIR
should be set: "Environment variables" and "Location of downloaded
packages". The former recommends setting BR2_DL_DIR in the .config,
the latter kind of endorses using ~/.bashrc.
We prefer suggesting the ~/.bashrc way since it avoids downloading the
same file multiple times, and anyway it's wise to have all the details
in a unique place. So remove the .config suggestion from "Environment
variables" and let it just point to "Location of downloaded packages".

Leverage the CSV files produces by size-stats (make graph-size) to allow
for a comparison of rootfs size between two different buildroot
compilations.
The script takes the file-size CSV files of two compilations as input, and
produces a textual report of the differences per package.
Using the -d/--detail flag, the report will show the file size changes
instead of package size changes.
The -t/--threshold option allows to ignore file size differences smaller
or equal than the given threshold (in bytes).
Example output is:
Size difference per package (bytes), threshold = 0

This patch performs some additional restructuring of the manual,
specifically in the User Guide. In detail:
- Rename 'Daily use' to 'General Buildroot usage'
- Move chapters 'make tips', 'Eclipse integration', and 'Advanced usage' as
sections under the 'General Buildroot usage' chapter.
- Rename 'Details on Buildroot configuration' into 'Buildroot configuration'
- Rework the 'Customization' section as follows:
- Move the short section on debugging the external toolchain wrapper into
the rest of the explanation on external toolchains.
- Remove the now redundant section on toolchains, as this is already
explained in much more detail in the 'Buildroot configuration' chapter.
- Move the sections on busybox/uclibc/kernel configuration from chapter
'Customization' into a separate chapter 'Configuration of other
components'.
- Rename the remaining part of the original 'Customization' chapter into
'Project-specific customization' and fold it together with the next
chapter 'Storing the configuration'
- Remove the chapter 'Going further in Buildroot innards' thanks to:
- Moving the chapter 'How Buildroot works' to the Developer guide.
- Moving the 'Advanced Buildroot usage' section to the 'General Buildroot
usage' chapter.
- Remove the chapter 'Hacking Buildroot' by:
- Adding a reference to adding packages to the 'Project-specific
customizations' chapter
- Leaving out the explicit reference to creating board support, as this is
part of the previous chapter already, so an extra reference is
redundant.

There will soon be new options to the graph-depends script, which we
can only sanely pass via environment variables.
Currently, we use such an environment variable to pass the maximum depth
of the dependency graph; the name of that variable is explicit that it
contains just the depth.
However, there has been so far no release of Buildroot which would make
use of that variable, so no user should have come to rely on it.
Rename that variable so it is less specific, and more generic, so it can
be used to pass more options to graph-depends.

Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.
For example, running this:
make -C buildroot O=my-O
will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O
Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.
Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

The new skeleton of the manual as it has been thought:
1. About Buildroot:
Presentation of Buildroot
2. Starting up:
Everything to quickly and easily start working with Buildroot
3. Working with Buildroot
Basics to make your work fitting your needs
4. Troubleshooting
5. Going further in Buildroot's innards
Explaination of how buildroot is organised, how it works, etc
6. Developer Guidelines
7. Getting involved
8. Contibuting to Buildroot
9. Legal notice
10. Appendix
It is easy to distinguish two parts in this plan:
- Sections 1 to 4 mainly address people starting with Buildroot
- Sections 5 to 10 are more focused on how to develop Buildroot itself
Most of the existing sections have just been moved in the hierarchy,
few were split and dispatch in, what i think was the relevant section,
and numerous others have been created.
