+*** Important Usage Notes ***
+
+1. If a constructor for A takes a pointer to an object B (except primitive
+types such as int and char), then A owns B and will delete B at A's
+destruction. If a constructor for A takes a reference to an object B,
+then the caller retains ownership of B and should not destroy it until
+A no longer needs it.
+
+2. Crypto++ is thread safe at the class level. This means you can use
+Crypto++ safely in a multithreaded application, but you must provide
+synchronization when multiple threads access a common Crypto++ object.
+
+*** MSVC-Specific Information ***
+
+On Windows, Crypto++ can be compiled into 3 forms: a static library
+including all algorithms, a DLL with only FIPS Approved algorithms, and
+a static library with only algorithms not in the DLL.
+(FIPS Approved means Approved according to the FIPS 140-2 standard.)
+The DLL may be used by itself, or it may be used together with the second
+form of the static library. MSVC project files are included to build
+all three forms, and sample applications using each of the three forms
+are also included.
+
+To compile Crypto++ with MSVC, open the "cryptest.dsw" (for MSVC 6 and MSVC .NET
+2003) or "cryptest.sln" (for MSVC .NET 2005) workspace file and build one or
+more of the following projects:
+
+cryptdll - This builds the DLL. Please note that if you wish to use Crypto++
+ as a FIPS validated module, you must use a pre-built DLL that has undergone
+ the FIPS validation process instead of building your own.
+dlltest - This builds a sample application that only uses the DLL.
+cryptest Non-DLL-Import Configuration - This builds the full static library
+ along with a full test driver.
+cryptest DLL-Import Configuration - This builds a static library containing
+ only algorithms not in the DLL, along with a full test driver that uses
+ both the DLL and the static library.
+
+To use the Crypto++ DLL in your application, #include "dll.h" before including
+any other Crypto++ header files, and place the DLL in the same directory as
+your .exe file. dll.h includes the line #pragma comment(lib, "cryptopp")
+so you don't have to explicitly list the import library in your project
+settings. To use a static library form of Crypto++, specify it as
+an additional library to link with in your project settings.
+In either case you should check the compiler options to
+make sure that the library and your application are using the same C++
+run-time libraries and calling conventions.
+
+*** DLL Memory Management ***
+
+Because it's possible for the Crypto++ DLL to delete objects allocated
+by the calling application, they must use the same C++ memory heap. Three
+methods are provided to achieve this.
+1. The calling application can tell Crypto++ what heap to use. This method
+ is required when the calling application uses a non-standard heap.
+2. Crypto++ can tell the calling application what heap to use. This method
+ is required when the calling application uses a statically linked C++ Run
+ Time Library. (Method 1 does not work in this case because the Crypto++ DLL
+ is initialized before the calling application's heap is initialized.)
+3. Crypto++ can automatically use the heap provided by the calling application's
+ dynamically linked C++ Run Time Library. The calling application must
+ make sure that the dynamically linked C++ Run Time Library is initialized
+ before Crypto++ is loaded. (At this time it is not clear if it is possible
+ to control the order in which DLLs are initialized on Windows 9x machines,
+ so it might be best to avoid using this method.)
+
+When Crypto++ attaches to a new process, it searches all modules loaded
+into the process space for exported functions "GetNewAndDeleteForCryptoPP"
+and "SetNewAndDeleteFromCryptoPP". If one of these functions is found,
+Crypto++ uses methods 1 or 2, respectively, by calling the function.
+Otherwise, method 3 is used.
+
+*** GCC-Specific Information ***
+
+A makefile is included for you to compile Crypto++ with GCC. Make sure
+you are using GNU Make and GNU ld. The make process will produce two files,
+libcryptopp.a and cryptest.exe. Run "cryptest.exe v" for the validation
+suite.
+
+*** Documentation and Support ***
+
+Crypto++ is documented through inline comments in header files, which are
+processed through Doxygen to produce an HTML reference manual. You can find
+a link to the manual from http://www.cryptopp.com. Also at that site is
+the Crypto++ FAQ, which you should browse through before attempting to
+use this library, because it will likely answer many of questions that
+may come up.
+
+If you run into any problems, please try the Crypto++ mailing list.
+The subscription information and the list archive are available on
+http://www.cryptopp.com. You can also email me directly by visiting
+http://www.weidai.com, but you will probably get a faster response through
+the mailing list.

+ - removed WORD64_AVAILABLE; compiler support for 64-bit int is now required
+ - ported to GCC 4.3, C++Builder 2009, Sun CC 5.10, Intel C++ Compiler 11

+ the number of bytes left to be processed, and can be used to implement a progress bar.
