+            svn     Subversion
+            wget    HTTP download
+
+    -o FILE
+        Store the downloaded archive in FILE.
+
+    -H FILE
+        Use FILE to read hashes from, and check them against the downloaded
+        archive.

+--- HOWTO ---
+If your package uses config.guess and/or config.sub, then it probably
+relies on the autotools as its build system. In this case, you should
+use the autotools-package infrastructure, which will take care of updating
+the config.guess and/or config.sub files appropriately. See the
+Buildroot documentation for details about the autotools-package
+infrastructure.
+
+If for some reason your package does not use the autotools-package
+infrastructure, you can request the config.guess and/or config.sub
+files of your package to be updated by using:
+
+      $(call CONFIG_UPDATE,directory-of-your-package-sources)
+
+--- UPDATE ---
+GNU config is now managed in git, so to update:
+
+# git clone git://git.savannah.gnu.org/config.git
+# cp config/config.* .
+# for p in $(ls patches/*.patch); do patch -p1 < $p; done
+# rm -rf config
+
+Currently no patches are needed, but they may be needed again in the
+future.
+
+The current Buildroot version is based on the Git commit
+dafd8e767ec87b90aac62f0fcedd11944c84b50a of the config.git repository.

+/*
+ *  Changes by Clifford Wolf (god@clifford.at)
+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+
+    support/kconfig: fix 'space' to (de)select options
+    
+    In case a menu has comment without letters/numbers (eg. characters
+    matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *),
+    hitting space will cycle through those comments, rather than
+    selecting/deselecting the currently-highlighted option.
+    
+    This is the behaviour of hitting any letter/digit: jump to the next
+    option which prompt starts with that letter. The only letters that
+    do not behave as such are 'y' 'm' and 'n'. Prompts that start with
+    one of those three letters are instead matched on the first letter
+    that is not 'y', 'm' or 'n'.
+    
+    Fix that by treating 'space' as we treat y/m/n, ie. as an action key,
+    not as shortcut to jump to  prompt.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This makes "make menuconfig" also work on systems where ncurses is not
+installed in a standard location (such as on NixOS).
+
+This patch changes ccflags() so that it tries pkg-config first, and only
+if pkg-config fails does it go back to the fallback/manual checks. This
+is the same algorithm that ldflags() already uses.

+
+I'm adding this instead of doing a full upstream kconfig sync because
+there was a conflict in one of the Buildroot kconfig patches (against
+linux 3.18-rc1), which I was unable to resolve. Just drop this patch next time

+Subject: kconfig: nconfig: fix multi-byte UTF handling
+
+Currently, Kconfig descriptions that use multi-byte UTF-8 characters
+(such as MTD_NAND_CAFE) will have their menu entries dropped from the
+'make nconfig' ncurses menu, and all subsequent entries in the same
+window will be omitted. This seems to be due to the ncurses 'menu'
+library, which does not traditionally handle UTF-8 >8-bit characters
+properly.
+
+The ncursesw library ('w' is for "wide") is written to handle these
+UTF-8 characters, and is practically a drop-in replacement at the source
+level. Use it by default, if available.

+#  It's simple enough to figure out how this works.
+#  If not, then you can ask me at stripconfig@goodmis.org
+#
+# What it does?
+#
+#   If you have installed a Linux kernel from a distribution
+#   that turns on way too many modules than you need, and
+#   you only want the modules you use, then this program
+#   is perfect for you.
+#
+#   It gives you the ability to turn off all the modules that are
+#   not loaded on your system.
+#
+# Howto:
+#
+#  1. Boot up the kernel that you want to stream line the config on.
+#  2. Change directory to the directory holding the source of the
+#       kernel that you just booted.
+#  3. Copy the configuraton file to this directory as .config
+#  4. Have all your devices that you need modules for connected and
+#      operational (make sure that their corresponding modules are loaded)
+#  5. Run this script redirecting the output to some other file
+#       like config_strip.
+#  6. Back up your old config (if you want too).
+#  7. copy the config_strip file to .config
+#  8. Run "make oldconfig"
+#
+#  Now your kernel is ready to be built with only the modules that
+#  are loaded.
+#
+# Here's what I did with my Debian distribution.
+#
+#    cd /usr/src/linux-2.6.10
+#    cp /boot/config-2.6.10-1-686-smp .config
+#    ~/bin/streamline_config > config_strip
+#    mv .config config_sav
+#    mv config_strip .config

+Most of the packages that were used by Buildroot to produce the image files,
+including Buildroot itself, have open-source licenses. It is your
+responsibility to comply to the requirements of these licenses.
+To make this easier for you, Buildroot collected in this directory some
+material you may need to get it done.
+
+This material is composed of the following items.
+ * The scripts used to control compilation of the packages and the generation
+   of image files, i.e. the Buildroot sources.
+   Note: this has not been saved due to technical limitations, you must
+   collect it manually.
+ * The Buildroot configuration file; this has been saved in buildroot.config.
+ * The toolchain (cross-compiler and related tools) used to generate all the
+   compiled programs.
+   Note: this may have not been saved due to technical limitations, you may
+   need to collect it manually.
+ * The original source code for all packages; this has been saved in the
+   sources/ subdirectory (except for the non-redistributable packages, which
+   have not been saved). Patches that were applied are also saved, along
+   with a file named 'series' that lists the patches in the order they were
+   applied. Patches are under the same license as the files that they modify
+   in the original package.
+   Note: Buildroot applies additional patches to Libtool scripts of
+   autotools-based packages. These patches can be found under
+   support/libtool in the Buildroot source and, due to technical
+   limitations, are not saved with the package sources. You may need
+   to collect them manually.

+Warning!
+========
+
+This directory does *not* contain the root filesystem that you can use
+on your embedded system. Since Buildroot does not run as root, it
+cannot create device files and set the permissions and ownership of
+files correctly in this directory to make it usable as a root
+filesystem.
+
+For that reason, do *not* use the contents of this directory to mount
+your root filesystem over NFS or copy the contents of this directory
+to a SD card or USB key, thinking it will work as the root filesystem
+for your embedded system. It will simply *not* work.
+
+Instead, if you need a usable root filesystem, please select one of
+the filesystem image formats available in the Buildroot configuration
+interface (make menuconfig or others) in the "Filesystem images"
+sub-menu. If you want to get a filesystem image that you can easily
+extract to your SD card or to some directory exposed through NFS,
+please use the "tar the root filesystem" option. It will generate a
+images/rootfs.tar image in your Buildroot output directory, which you
+can extract as root:
+
+  sudo tar -C /destination/of/extraction -xf images/rootfs.tar
+
+Those image files are created using the contents of the target/
+directory, but there is a post-processing step to create device files
+and set owernship/permissions properly even if Buildroot does not run
+as root.

+# A little script I whipped up to make it easy to
+# patch source trees and have sane error handling
+# -Erik
+#
+# (c) 2002 Erik Andersen <andersen@codepoet.org>
+#
+# Parameters:
+# - "-s", optional. Silent operation, don't print anything if there
+# isn't any error.
+# - the build directory, optional, default value is '.'. The place where are
+# the package sources.
+# - the patch directory, optional, default '../kernel-patches'. The place
+# where are the scripts you want to apply.
+# - other parameters are the patch name patterns, optional, default value is
+# '*'. Pattern(s) describing the patch names you want to apply.
+#
+# The script will look recursively for patches from the patch directory. If a
+# file named 'series' exists then the patches mentioned in it will be applied
+# as plain patches, regardless of their file name. If no 'series' file exists,
+# the script will look for file names matching pattern(s). If the name
+# ends with '.tar.*', '.tbz2' or '.tgz', the file is considered as an archive
+# and will be uncompressed into a directory named
+# '.patches-name_of_the_archive-unpacked'. It's the turn of this directory to
+# be scanned with '*' as pattern. Remember that scanning is recursive. Other
+# files than series file and archives are considered as a patch.
+#
+# Once a patch is found, the script will try to apply it. If its name doesn't
+# end with '.gz', '.bz', '.bz2', '.xz', '.zip', '.Z', '.diff*' or '.patch*',
+# it will be skipped. If necessary, the patch will be uncompressed before being
