+ MAG_DDR DDR macro for the reader's port (i.e.. DDRC)
+ MAG_PORT PORT macro for the reader's port (i.e.. PORTC)
+
+ The example macros listed above assume that the Track 2 data wire is

+ pin that is unused. For example, on the AT90USBKey, any of the pins on
+ port C that do not have wires attached will be unused since they are
+ not connected to any onboard devices (such as the joystick or
+ temperature sensor).
+
+ Connecting wires to pins on different ports (i.e.. a data wire to pin 0
+ on port C and a clock wire to pin 0 on port D) is currently
+ unsupported. All pins specified above must be on the same port.

+ *

+ *
+ * <table>

+ * <td><b>USB Mode:</b></td>

+ * \section Sec_Description Project Description:
+ *
+ * Firmware for a USB AVR powered USB TTL magnetic stripe reader (using a card
+ * reader such as the Omron V3B-4K) by Denver Gingerich. This project is designed
+ * to be used with the open source Stripe Snoop project at <a>http://stripesnoop.sourceforge.net/</a>.
+ *
+ * See <a>http://ossguy.com/ss_usb/</a> for the USB reader hardware project website,
+ * including construction and support details.
+ *
+ * To use, connect your magnetic card reader device to the USB AVR as follows (pin and port mapping may be adjusted
+ * from the project makefile):
+ *
+ * <table>
+ * <tr>
+ * <th><b>Signal:</b></th>
+ * <th><b>AVR Port:</b></th>
+ * </tr>
+ * <tr>
+ * <td>Track 1 Data</td>
+ * <td>PORTC, Pin 1</td>

+ * </tr>
+ * </table>
+ *
+ * This project is based on the LUFA Keyboard project demonstration application, written by Denver Gingerich.
+ *
+ * This application uses a keyboard HID driver to communicate the data collected a TTL magnetic stripe reader
+ * to the connected computer. The raw bitstream obtained from the magnetic stripe reader is "typed" through
+ * the keyboard driver as 0's and 1's. After every card swipe, the project will send a return key.
+ *

+
+# This file describes the settings to be used by the documentation system
+# doxygen (www.doxygen.org) for a project.
+#
+# All text after a double hash (##) is considered a comment and is placed in
+# front of the TAG it is preceding.
+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:
+# TAG += value [value, ...]
+# Values that contain spaces should be placed between quotes (\" \").
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
+
+DOXYFILE_ENCODING = UTF-8
+
+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
+# double-quotes, unless you are using Doxywizard) that should identify the
+# project for which the documentation is generated. This name is used in the
+# title of most generated pages and in a few other places.
+# The default value is: My Project.
+
+PROJECT_NAME = "Denver Gingerich's Stripe Snoop Project"

+# The PROJECT_NUMBER tag can be used to enter a project or revision number. This
+# could be handy for archiving the generated documentation or if some version

+PROJECT_NUMBER =
+
+# Using the PROJECT_BRIEF tag one can provide an optional one line description
+# for a project that appears at the top of each page and should give viewer a
+# quick idea about the purpose of the project. Keep the description short.

+PROJECT_BRIEF =
+
+# With the PROJECT_LOGO tag one can specify a logo or an icon that is included

+# pixels and the maximum width should not exceed 200 pixels. Doxygen will copy
+# the logo to the output directory.

+
+# The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) path

+# If the CREATE_SUBDIRS tag is set to YES then doxygen will create 4096 sub-
+# directories (in 2 levels) under the output directory of each output format and
+# will distribute the generated files over these directories. Enabling this
+# option can be useful when feeding doxygen a huge amount of source files, where
+# putting all generated files in the same directory would otherwise causes
+# performance problems for the file system.
+# The default value is: NO.

+# U+3044.

+
+# The OUTPUT_LANGUAGE tag is used to specify the language in which all
+# documentation generated by doxygen is written. Doxygen will use this
+# information to generate all constant output in the proper language.
+# Possible values are: Afrikaans, Arabic, Armenian, Brazilian, Catalan, Chinese,
+# Chinese-Traditional, Croatian, Czech, Danish, Dutch, English (United States),
+# Esperanto, Farsi (Persian), Finnish, French, German, Greek, Hungarian,

+# This tag implements a quasi-intelligent brief description abbreviator that is
+# used to form the text in various listings. Each string in this list, if found
+# as the leading text of the brief description, will be stripped from the text
+# and the result, after processing the whole list, is used as the annotated
+# text. Otherwise, the brief description is used as-is. If left blank, the
+# following values are used ($name is automatically replaced with the name of

+# to treat a multi-line C++ comment block as a detailed description. Set this
