+Intel HEX Class Project
+=======================
+
+Introduction to the Intel HEX Class Module
+------------------------------------------
+The Intel HEX Class Module is designed to allow the programmer to easily work with Intel HEX files. Using standard C++ stream operators it is possible to decode a file into memory and then to examine the entire content of the file much more easily than if the original file was simply opened in a text editor.
+
+Additionally, again using a C++ stream operator, it is possible to encode the current data in memory back into Intel HEX format again straight to a file.
+
+Using this class it is also possible to:
+
+* Generate Intel HEX files with your own content
+* Fill blank areas of an Intel HEX file with a desired value or pattern
+* Merge two or more files together
+* Selectively merge parts of two or more files together
+* Check an Intel HEX file for correctness and integrity (correct construction, checksums ok, etc.)
+
+Key Software Capabilities
+-------------------------
+* Stream Intel HEX file content into class for decoding
+* Stream data stored in memory out from class in Intel HEX format to a file
+* 'Never give up' approach to decoding; warning and error messages can be examined upon completion; as much as humanely possible will have been decoded.
+* Class contains no 'try' calls; will always return cleanly for programmer to make decision how to proceed.
+* File sizes up to 4GB supported (system dependent).
+* All records as per the official Intel "Hexadecimal Object File Format Specification, Revision A, January 6, 1988" supported
