-Manual Makefile
----------------
-
-*NOTE: new manual makefiles should not be created, and existing manual
-makefiles should be converted either to the generic, autotools or
-cmake infrastructure. This section is only kept to document the
-existing manual makefiles and to help understand how they work.*

-------------------------
-
-First of all, this Makefile example works for a package which
-comprises a single binary executable. For other software, such as
-libraries or more complex stuff with multiple binaries, it must be
-qqadapted. For examples look at the other +*.mk+ files in the
-+package+ directory.
-
-At lines 6-11, a couple of useful variables are defined:
-
-* +LIBFOO_VERSION+: The version of 'libfoo' that should be downloaded.
-
-* +LIBFOO_SOURCE+: The name of the tarball of 'libfoo' on the download
- website or FTP site. As you can see +LIBFOO_VERSION+ is used.
-
-* +LIBFOO_SITE+: The HTTP or FTP site from which 'libfoo' archive is
- downloaded. It must include the complete path to the directory where
- +LIBFOO_SOURCE+ can be found.
-
-* +LIBFOO_DIR+: The directory into which the software will be
- configured and compiled. Basically, it's a subdirectory of
- +BUILD_DIR+ which is created upon decompression of the tarball.
-
-* +LIBFOO_BINARY+: Software binary name. As said previously, this is
- an example for a package with a single binary.
-
-* +LIBFOO_TARGET_BINARY+: The full path of the binary inside the
- target filesystem. Lines 13-14 define a target that downloads the
- tarball from the remote site to the download directory (+DL_DIR+).
-
-Lines 16-18 define a target and associated rules that uncompress the
-downloaded tarball. As you can see, this target depends on the tarball
-file so that the previous target (lines 13-14) is called before
-executing the rules of the current target. Uncompressing is followed
-by 'touching' a hidden file to mark the software as having been
-uncompressed. This trick is used everywhere in a Buildroot Makefile to
-split steps (download, uncompress, configure, compile, install) while
-still having correct dependencies.
-
-Lines 20-31 define a target and associated rules that configure the
-software. It depends on the previous target (the hidden +.source+
-file) so that we are sure the software has been uncompressed. In order
-to configure the package, it basically runs the well-known
-+./configure+ script. As we may be doing cross-compilation, +target+,
-+host+ and +build+ arguments are given. The prefix is also set to
-+/usr+, not because the software will be installed in +/usr+ on your
-host system, but because the software will be installed in + /usr+ on
-the target filesystem. Finally it creates a +.configured+ file to mark
-the software as configured.
-
-Lines 33-34 define a target and a rule that compile the software. This
-target will create the binary file in the compilation directory and
-depends on the software being already configured (hence the reference
-to the +.configured+ file). It basically runs +make+ inside the
-source directory.
-
-Lines 36-38 define a target and associated rules that install the
-software inside the target filesystem. They depend on the binary file
-in the source directory to make sure the software has been
-compiled. They use the +install-strip+ target of the software
-+Makefile+ by passing a +DESTDIR+ argument so that the +Makefile+
-doesn't try to install the software in the host +/usr+ but rather in
-the target +/usr+. After the installation, the +/usr/man + directory
-inside the target filesystem is removed to save space.
-
-Line 40 defines the main target of the software — the one that
-will eventually be used by the top level +Makefile+ to download,
-compile, and then install this package. This target should first of
-all depend on all needed dependencies of the software (in our example,
-'uclibc' and 'ncurses') and also depend on the final binary. This last
-dependency will call all previous dependencies in the correct order.
-
-Line 42 defines a simple target that only downloads the code
-source. This is not used during normal operation of Buildroot, but is
-needed if you intend to download all required sources at once for
-later offline build. Note that if you add a new package, providing a
-+libfoo-source+ target is 'mandatory' to support users that wish to do
-offline-builds. Furthermore, it eases checking if all package-sources
-are downloadable.
-
-Lines 44-46 define a simple target to clean the software build by
-calling the Makefile with the appropriate options. The +-clean+
-target should run +make clean+ on $(BUILD_DIR)/package-version and
-MUST uninstall all files of the package from $(STAGING_DIR) and from
-$(TARGET_DIR).
-
-Lines 48-49 define a simple target to completely remove the directory
-in which the software was uncompressed, configured and compiled. The
-+-dirclean+ target MUST completely rm $(BUILD_DIR)/ package-version.
-
-Lines 51-58 add the target +libfoo+ to the list of targets to be
-compiled by Buildroot, by first checking if the configuration option
-for this package has been enabled using the configuration tool. If so,
-it then "subscribes" this package to be compiled by adding
-the package to the TARGETS global variable. The name added to the
-TARGETS global variable is the name of this package's target, as
-defined on line 40, which is used by Buildroot to download, compile,
-and then install this package.
