manual: use one-line titles instead of two-line titles (trivial) 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. ---------------------------------------------------------------------------- #!/usr/bin/env python import sys import mmap import re for input in sys.argv[1:]: f = open(input, 'r+') f.flush() s = mmap.mmap(f.fileno(), 0) # Level 0 (top level): ====================== = # Level 1: ---------------------- == # Level 2: ~~~~~~~~~~~~~~~~~~~~~~ === # Level 3: ^^^^^^^^^^^^^^^^^^^^^^ ==== # Level 4 (bottom level): ++++++++++++++++++++++ ===== def replace_title(s, symbol, replacement): pattern = re.compile(r'(.+\n)\%s{2,}\n' % symbol, re.MULTILINE) return pattern.sub(r'%s \1' % replacement, s) new = s new = replace_title(new, '=', '=') new = replace_title(new, '+', '=====') new = replace_title(new, '^', '====') new = replace_title(new, '~', '===') #new = replace_title(new, '-', '==') s.seek(0) s.write(new) s.resize(s.tell()) s.close() f.close() ---------------------------------------------------------------------------- Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

== System requirements
Buildroot is designed to run on Linux systems.
Buildroot needs some software to be already installed on the host
system; here are the lists of the mandatory and optional packages
(package names may vary between distributions).
Take care to _install both runtime and development data_, especially
for the libraries that may be packaged in 2 distinct packages.

=== Optional packages
* Source fetching tools:
+
In the official tree, most of the package sources are retrieved
using +wget+; a few are only available through their +git+, +mercurial+,
+svn+ or +cvs+ repository.
+
All other source fetching methods are implemented and may be used in a
development context (further details: refer to xref:download-infra[]).
+
** +bazaar+
** +cvs+
** +git+
** +mercurial+
** +rsync+
** +scp+
** +subversion+
* Configuration interface dependencies (requires development libraries):
** +ncurses5+ to use the 'menuconfig' interface
** +qt4+ to use the 'xconfig' interface
** +glib2+, +gtk2+ and +glade2+ to use the 'gconfig' interface
* Java-related packages, if the Java Classpath needs to be built for
the target system:
** The +javac+ compiler
** The +jar+ tool
* Documentation generation tools:
** +asciidoc+, version 8.6.3 or higher
** +w3m+
** +python+ with the +argparse+ module (automatically present in 2.7+ and 3.2+)
** +dblatex+ (required for the pdf manual only)
* Graph generation tools:
** +graphviz+ to use 'graph-depends' and '<pkg>-graph-depends'
** +python-matplotlib+ to use 'graph-build'
