+// Why base-58 instead of standard base-64 encoding?
+// - Don't want 0OIl characters that look the same in some fonts and
+//      could be used to create visually identical looking account numbers.
+// - A string with non-alphanumeric characters is not as easily accepted as an account number.
+// - E-mail usually won't line-break if there's no punctuation to break at.
+// - Doubleclicking selects the whole number as one word if it's all alphanumeric.

+
+
+OpenSSL
+-------
+Bitcoin does not use any encryption.  If you want to do a no-everything
+build of OpenSSL to exclude encryption routines, a few patches are required.
+(OpenSSL v0.9.8h)
+
+Edit engines\e_gmp.c and put this #ifndef around #include <openssl/rsa.h>
+  #ifndef OPENSSL_NO_RSA
+  #include <openssl/rsa.h>
+  #endif
+
+Add this to crypto\err\err_all.c before the ERR_load_crypto_strings line:
+  void ERR_load_RSA_strings(void) { }
+
+Edit ms\mingw32.bat and replace the Configure line's parameters with this
+no-everything list.  You have to put this in the batch file because batch
+files can't handle more than 9 parameters.
+  perl Configure mingw threads no-rc2 no-rc4 no-rc5 no-idea no-des no-bf no-cast no-aes no-camellia no-seed no-rsa no-dh
+
+Also REM out the following line in ms\mingw32.bat.  The build fails after it's
+already finished building libeay32, which is all we care about, but the
+failure aborts the script before it runs dllwrap to generate libeay32.dll.
+  REM  if errorlevel 1 goto end
+
+Build
+  ms\mingw32.bat
+
+If you want to use it with MSVC, generate the .lib file
+  lib /machine:i386 /def:ms\libeay32.def /out:out\libeay32.lib
+
+
+Berkeley DB
+-----------
+MinGW with MSYS:
+cd \DB\build_unix
+sh ../dist/configure --enable-mingw --enable-cxx
+make
+
+
+Boost
+-----
+You may need Boost version 1.35 to build with MSVC 6.0.  I couldn't get
+version 1.37 to compile with MSVC 6.0.
