+===================================
+
+
+Modules Overview
+----------------
+
+The following modules are currently included:
+
+ - [ATPROGRAM](atprogram.md) - Device Programming
+ - [AVRDUDE](avrdude.md) - Device Programming
+ - [CORE](core.md) - DMBS Core Functionality
+ - [CPPCHECK](cppcheck.md) - Static Code Analysis
+ - [DFU](dfu.md) - Device Programming
+ - [DOXYGEN](doxygen.md) - Automated Source Code Documentation
+ - [GCC](gcc.md) - Compiling/Assembling/Linking with GCC
+ - [HID](hid.md) - Device Programming
+
+## Importing modules into your project makefile
+
+To use a module, it is recommended to add the following boilerplate to your
+makefile:
+
+    # Include DMBS build script makefiles
+    DMBS_PATH   ?= ../DMBS
+
+Which can then used to indicate the location of your DMBS installation, relative
+to the current directory, when importing modules. For example:
+
+    DMBS_PATH   ?= ../DMBS
+    include $(DMBS_PATH)/core.mk
+    include $(DMBS_PATH)/gcc.mk
+
+Imports the `CORE` and `GCC` modules from DMBS using a single path relative to
+your project's makefile.
+
+If you wish to write your own DMBS module(s),
+[see the documentation here for more details.](WritingYourOwnModules.md)

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Writing Your Own Modules
+------------------------
+
+A DMBS module consists of the several boilerplate sections, explained below.
+
+## The DMBS module hooks
+
+Your module needs to advertise to DMBS its name, its makefile targets, the
+required and optional variables, and the variables and macros the module
+provides for use elsewhere. This is achieved with the following section:
+
+    DMBS_BUILD_MODULES         += EXAMPLE
+    DMBS_BUILD_TARGETS         += example-target another-target
+    DMBS_BUILD_MANDATORY_VARS  += MANDATORY_NAME ALSO_MANDATORY
+    DMBS_BUILD_OPTIONAL_VARS   += OPTIONAL_NAME ALSO_OPTIONAL
+    DMBS_BUILD_PROVIDED_VARS   += MEANING_OF_LIFE
+    DMBS_BUILD_PROVIDED_MACROS += STRIP_WHITESPACE
+
+The example above declares that this module is called `EXAMPLE`, and exposes the
+listed targets, variable requirements and provides variables and macros.
+
+Your module name and provided variable/macro names must be unique, however you
+can (and should) re-use variable names where appropriate if they apply to
+several modules (such as `ARCH` to specify the project's microcontroller
+architecture). Re-using targets is not recommended, but can be used to extend
+the dependencies of another module's targets.
+
+## Importing the CORE module
+
+Next, your module should always import the DMBS `CORE` module, via the
+following:
+
+    # Conditionally import the CORE module of DMBS if it is not already imported
+    DMBS_MODULE_PATH := $(patsubst %/,%,$(dir $(lastword $(MAKEFILE_LIST))))
+    ifeq ($(findstring CORE, $(DMBS_BUILD_MODULES)),)
+      include $(DMBS_MODULE_PATH)/core.mk
+    endif
+
+This ensures that the `make help` target is always available. In addition, the
+`CORE` module exposes some [commonly used macros and variables](core.md) to
+your module.
+
+## Setting optional variable's defaults
+
+If a variable is optional, you should provide a default value. Do this via the
+`?=` operator of `make`, which sets a variable's value if it has not yet been
+set:
+
+    MY_OPTIONAL_VARIABLE ?= some_default_value
+
+## Sanity checking user input
+
+Sanity checks are what make DMBS useful. Where possible, validate user input and
+convert generated errors to human-friendly messages. This can be achieved by
+enforcing that all the declared module mandatory variables have been set by the
+user:
+
+    # Sanity-check values of mandatory user-supplied variables
+    $(foreach MANDATORY_VAR, $(DMBS_BUILD_MANDATORY_VARS), $(call ERROR_IF_UNSET, $(MANDATORY_VAR)))
+
+As well as complaining if they are set, but currently empty:
+
+    $(call ERROR_IF_EMPTY, SOME_MANDATORY_VARIABLE)
+    $(call ERROR_IF_EMPTY, SOME_OPTIONAL_BUT_NON_EMPTY_VARIABLE)
+
+Or even if they are boolean (`Y` or `N`) variables that have an invalid value:
+
+    $(call ERROR_IF_NONBOOL, SOME_BOOL_VARIABLE)
+
+## Adding targets
+
+The meat of a DMBS module is the targets, which are run when the user types
+`make {target name}` from the command line. These can be as complex or simple
+as you like. See the GNU make manual for information on writing make targets.
+
+    example-target:
+        echo "Your DMBS module works!"
+
+## And finally, list the PHONYs
+
+Important in GNU Make is the concept of phony targets; this special directive
+tells make that a given target should never be considered a valid file. Listing
+phonies ensures that, for example, if your module had a target called `build`,
+it would always run when the user types `make build` from the command line, even
+if a file called `build` existed in the user project folder.
+
+You can list module-internal targets here, as well as mark all public targets
+via the module header's `DMBS_BUILD_TARGETS` variable.
+
+    # Phony build targets for this module
+    .PHONY: $(DMBS_BUILD_TARGETS) some-module-internal-target another-internal-target

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Module: ATPROGRAM
+-----------------
+
+The ATPROGRAM module provides build targets for use with the official
+`ATPROGRAM` back-end utility distributed with the free
+[Atmel Studio](http://www.atmel.com) software released by Atmel.
+
+## Importing This Module into a Makefile:

+system's `PATH` variable. The `atprogram.exe` utility is distributed in Atmel
+Studio (usually) inside the application install folder's `atbackend`
+subdirectory.
+
+## Build Targets:
+
+The following targets are supported by this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>atprogram</td>
+    <td>Program the device FLASH memory with the application's executable data.</td>
+   </tr>
+   <tr>
+    <td>atprogram-ee</td>
+    <td>Program the device EEPROM memory with the application's EEPROM data.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Mandatory Variables:

+   </tr>
+   <tr>
+    <td>TARGET</td>
+    <td>Name of the application output file prefix (e.g. `TestApplication`).</td>
+   </tr>
+ </tbody>
+</table>
+
+## Optional Variables:
+
+The following variables may be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile. If not specified, a default value will
+be assumed.
+
+<table>
+ <tbody>
+   <tr>
+    <td>ATPROGRAM_PROGRAMMER</td>

+   </tr>
+   <tr>
+    <td>ATPROGRAM_INTERFACE</td>
+    <td>Name of the programming interface to use when programming the target (e.g. `spi`). Default is `jtag`.</td>
+   </tr>
+   <tr>
+    <td>ATPROGRAM_PORT</td>
+    <td>Name of the communication port to use when when programming with a serially connected tool (e.g. `COM2`). Default is `usb`.</td>

+===================================
+
+
+Module: AVRDUDE
+-----------------
+
+The AVRDUDE module provides build targets for use with the official
+open source `AVRDUDE` programmer utility, for the reprogramming of Atmel devices

+   </tr>
+ </tbody>
+</table>
+
+## Provided Variables:
+
+The following variables may be referenced in a user makefile (via `$(NAME)`
+syntax) if desired, as they are provided by this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Module: CORE
+------------
+
+The CORE module provides the core DMBS infrastructure used by other DMBS
+modules, and must always be imported. Additionally, this module provides the
+help system for DMBS.
+
+## Importing This Module into a Makefile:
+
+To use this module in your application makefile, add the following code to your
+makefile:
+
+    include $(DMBS_PATH)/core.mk
+
+## Prerequisites:
+
+None.
+
+## Build Targets:
+
+The following targets are supported by this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>help</td>
+    <td>Show help for the current project, including a list of all available targets, variables and macros from the imported modules.</td>
+   </tr>
+   <tr>
+    <td>list_targets</td>
+    <td>Show a list of all build targets from the imported modules.</td>

+   <tr>
+    <td>N/A</td>
+    <td>This module has no mandatory variables.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Optional Variables:
+
+The following variables may be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile. If not specified, a default value will
+be assumed.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module has no optional variables.</td>
+   </tr>

+   <tr>
+    <td>DMBS_VERSION</td>
+    <td>Current version of this DMBS release, as a ISO 8601 integer (such as `20160403` for `2016-04-03`).</td>
+   </tr>
+ </tbody>
+</table>
+
+## Provided Macros:
+
+The following macros may be referenced in a user makefile (via
+`$(call NAME, ARG1, ARG2, ...)` syntax) if desired, as they are provided by
+this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>DMBS_CHECK_VERSION</td>
+    <td>Macro to check the current DMBS version against the first argument and abort if the required version is newer than the current version.</td>
+   </tr>
+   <tr>
+    <td>ERROR_IF_UNSET</td>
+    <td>Macro to check the given makefile variable name passed as the first argument, and abort if it has not been set by any makefile module.</td>
+   </tr>
+   <tr>
+    <td>ERROR_IF_EMPTY</td>
+    <td>Macro to check the given makefile variable name passed as the first argument, and abort if it has an empty value.</td>
+   </tr>
+   <tr>
+    <td>ERROR_IF_NONBOOL</td>
+    <td>Macro to check the given makefile variable name passed as the first argument, and abort if it has a value other than `Y` or `N`.</td>

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Module: CPPCHECK
+-----------------
+
+The CPPCHECK module provides build targets to perform static analysis of the
+user application, using the open source `cppcheck` tool.
+
+## Importing This Module into a Makefile:
+
+To use this module in your application makefile, add the following code to your
+makefile:
+
+    include $(DMBS_PATH)/cppcheck.mk
+
+## Prerequisites:
+
+This module requires the `cppcheck` utility to be available in your system's
+`PATH` variable. The `cppcheck` utility is distributed on the project's
+[official site](http://cppcheck.sourceforge.net/) but is also
+made available in many *nix operating system's package managers.
+
+## Build Targets:
+
+The following targets are supported by this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>cppcheck</td>
+    <td>Scan the project with CPPCHECK, and show all discovered issues.</td>
+   </tr>
+   <tr>
+    <td>cppcheck-config</td>
+    <td>Check the project with CPPCHECK, to find missing header paths.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Mandatory Variables:
+
+The following variables must be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile to be able to use this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>SRC</td>
+    <td>List of all project source files to scan.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Optional Variables:
+
+The following variables may be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile. If not specified, a default value will
+be assumed.
+
+<table>
+ <tbody>
+   <tr>
+    <td>CPPCHECK_INCLUDES</td>
+    <td>Extra include paths to search, for any missing header files. Default is empty (no additional paths).</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_EXCLUDES</td>
+    <td>List of source files, file paths or path fragments to exclude from the scan. Default is empty (no exclusions).</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_MSG_TEMPLATE</td>
+    <td>Template for error and warning message output. Default is `{file}:{line}: {severity} ({id}): {message}`.</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_ENABLE</td>
+    <td>List of CPPCHECK checks to enable. Default is `all`.</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_SUPPRESS</td>
+    <td>List of CPPCHECK checks to ignore. Default is `variableScope missingInclude`.</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_FAIL_ON_WARNING</td>
+    <td>Boolean, if `Y` the build will fail if CPPCHECK discovers any errors or warnings. If `N`, fail only on errors. Default is `Y`.</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_QUIET</td>
+    <td>Boolean, if `Y` CPPCHECK will suppress all output except for discovered errors or warnings. If `N`, scan progress will be emitted. Default is `Y`.</td>
+   </tr>
+   <tr>
+    <td>CPPCHECK_FLAGS_</td>
+    <td>Additional flags to pass to CPPCHECK when scans are started. Default is empty (no additional flags).</td>
+   </tr>
+ </tbody>
+</table>
+
+## Provided Variables:
+
+The following variables may be referenced in a user makefile (via `$(NAME)`
+syntax) if desired, as they are provided by this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module provides no variables.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Provided Macros:
+
+The following macros may be referenced in a user makefile (via
+`$(call NAME, ARG1, ARG2, ...)` syntax) if desired, as they are provided by
+this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module provides no macros.</td>

+===================================
+
+
+Module: DFU
+-----------------
+
+The DFU module provides build targets to program a USB connected target running
+a DFU class bootloader, via the official Atmel FLIP utility running via the
+command line, or the open source `DFU-Programmer` tool.
+
+## Importing This Module into a Makefile:

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Module: HID
+-----------------
+
+The HID module provides build targets to program a target running a PJRC Teensy
+or LUFA compatible HID class bootloader.
+
+## Importing This Module into a Makefile:
+
+To use this module in your application makefile, add the following code to your
+makefile:
+
+    include $(DMBS_PATH)/hid.mk
+
+## Prerequisites:
+
+This module requires the `teensy_loader_cli` utility to be available in your
+system's `PATH` variable. The `teensy_loader_cli` utility is distributed in
+a modified form (from PJRC) in the LUFA project's
+[official site](http://www.lufa-lib.org/), but is also
+made available in its original form directly from the 
+[PJRC website](https://www.pjrc.com/teensy/loader_cli.html). Note that the
+original tool works with Teensy boards only, and not LUFA HID bootloader
+devices.
+
+This module requires the `hid_bootloader_cli` utility to be available in your
+system's `PATH` variable. The `hid_bootloader_cli` Python script utility is
+distributed in LUFA project's [official site](http://www.lufa-lib.org/).
+
+This module requires the AVR-GCC compiler to be installed and available in the
+system's `PATH` variable.
+
+## Build Targets:
+
+The following targets are supported by this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>hid</td>
+    <td>Program a LUFA HID class bootloader device, using the `hid_bootloader_cli.py` Python script.</td>
+   </tr>
+   <tr>
+    <td>hid-ee</td>
+    <td>Program a LUFA HID class bootloader device's EEPROM, using the `hid_bootloader_cli.py` Python script and a shim application which is programmed into the target's flash.</td>
+   </tr>
+   <tr>
+    <td>teensy</td>
+    <td>Program a LUFA HID class bootloader device or Teensy board, using the `teensy_loader_cli` tool.</td>
+   </tr>
+   <tr>
+    <td>teensy-ee</td>
+    <td>Program a LUFA HID class bootloader device's EEPROM, using the `teensy_loader_cli` tool and a shim application which is programmed into the target's flash.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Mandatory Variables:
+
+The following variables must be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile to be able to use this module:
+
+<table>
+ <tbody>
+   <tr>
+    <td>MCU</td>
+    <td>Name of the Atmel processor model (e.g. `at90usb1287`).</td>
+   </tr>
+   <tr>
+    <td>TARGET</td>
+    <td>Name of the application output file prefix (e.g. `TestApplication`).</td>
+   </tr>   
+ </tbody>
+</table>
+
+## Optional Variables:
+
+The following variables may be defined (with a `NAME = VALUE` syntax, one
+variable per line) in the user makefile. If not specified, a default value will
+be assumed.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module has no optional variables.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Provided Variables:
+
+The following variables may be referenced in a user makefile (via `$(NAME)`
+syntax) if desired, as they are provided by this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module provides no variables.</td>
+   </tr>
+ </tbody>
+</table>
+
+## Provided Macros:
+
+The following macros may be referenced in a user makefile (via
+`$(call NAME, ARG1, ARG2, ...)` syntax) if desired, as they are provided by
+this module.
+
+<table>
+ <tbody>
+   <tr>
+    <td>N/A</td>
+    <td>This module provides no macros.</td>
+   </tr>
+ </tbody>
+</table>
+

+DMBS - Dean's Makefile Build System
+===================================
+
+
+Project Overview
+----------------
+
+GNU Make is scary, and it's tough to get the rules right sometimes. Many
+projects get by via simple copy-pasting of old makefiles, resulting in many
+redundant copies of the same old rules. DMBS aims to solve this by providing a
+simple modular set of makefiles which can be included by your project to quickly
+add various build functionality.
+
+This aims to replace the old WinAVR "mfile" makefile template, giving better
+functionality and much simpler user makefiles.
+
+
+Benefits:
+----------------
+
+Apart from much simpler, cleaner makefiles DMBS carries the aim of making the
+process of troubleshooting build issues a little easier. Lots can go wrong, so
+DMBS tries to sanity check its inputs wherever possible, and produce
+human-readable error messages. Forgotten to set a variable? Get a
+`Makefile {X} value not set.` message, rather than a possibly unrelated message.
+Have the wrong filename? See `Source file does not exist: {X}` rather than the
+infamous `No rule to make target {X}` message.
+
+
+Use:
+----------------
+
+A template user makefile is provided in the `Template` directory. DMBS modules
+are included via a GNU Make `include` directive. While the DMBS `core` module is
+always required, you can pick and choose what other modules you wish to add to
+your user project.
+
+[See here for the documentation on the individual modules provided by DMBS.](DMBS/ModulesOverview.md)
+If you're interested in writing your own DMBS module(s), [see here.](DMBS/WritingYourOwnModules.md)
+
+Here's an example user makefile:
+
+	MCU          = atmega128
+	ARCH         = AVR8
+	F_CPU        = 8000000
+	OPTIMIZATION = s
+	TARGET       = Template
+	SRC          = $(TARGET).c
+	CC_FLAGS     =
+	LD_FLAGS     =
+
+	# Default target
+	all:
+
+	# Include DMBS build script makefiles
+	DMBS_PATH   ?= ../DMBS
+	include $(DMBS_PATH)/core.mk
+	include $(DMBS_PATH)/gcc.mk
+	include $(DMBS_PATH)/cppcheck.mk
+	include $(DMBS_PATH)/doxygen.mk
+	include $(DMBS_PATH)/dfu.mk
+	include $(DMBS_PATH)/hid.mk
+	include $(DMBS_PATH)/avrdude.mk
+	include $(DMBS_PATH)/atprogram.mk
+
+Each DMBS module can optionally supply one or more Make variables and macros,
+which you can reference in your user makefile. Additionally, modules can require
+one or more variables to be set by the user makefile, with (in some cases) sane
+defaults used if left out.
+
+As modules are added, you can get a list of available targets by simply typing
+`make help` from the command line. This will produce a formatted list of targets
+as well as mandatory and optional variables and exposed variables and macros.
+
+
+Distribution
+----------------
+
+You can embed DMBS in your project any way you like - some options are:
+1. A git submodule
+2. A source tarball
+3. A manually copied extracted archive
+
+The intention of DMBS is that users can just import it from whatever source
+they like. If your project needs to extend the existing modules in an unusual
+manner, or if you want to provide your own modules, you can include them in
+your project repository (or submit a patch to DMBS if your module is generic
+enough to warrant wide use).
+

+by everyone. Contributions are greatly appreciated however, in order to make
