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.

=== Location of downloaded packages
|
|
|
|
The various tarballs that are downloaded by Buildroot are all stored
|
|
in +BR2_DL_DIR+, which by default is the +dl+ directory. If you want
|
|
to keep a complete version of Buildroot which is known to be working
|
|
with the associated tarballs, you can make a copy of this directory.
|
|
This will allow you to regenerate the toolchain and the target
|
|
filesystem with exactly the same versions.
|
|
|
|
If you maintain several Buildroot trees, it might be better to have a
|
|
shared download location. This can be achieved by pointing the
|
|
+BR2_DL_DIR+ environment variable to a directory. If this is
|
|
set, then the value of +BR2_DL_DIR+ in the Buildroot configuration is
|
|
overridden. The following line should be added to +<~/.bashrc>+.
|
|
|
|
-----------------
|
|
$ export BR2_DL_DIR <shared download location>
|
|
-----------------
|
|
|
|
The download location can also be set in the +.config+ file, with the
|
|
+BR2_DL_DIR+ option. Unlike most options in the .config file, this value
|
|
is overridden by the +BR2_DL_DIR+ environment variable.
