 Legacy Windows and SSL
 ======================
-Some of the project configurations use as an SSL backend WinSSL (Windows SSPI,
-more specifically Schannel), the native SSL library that comes with the Windows
-OS. WinSSL in Windows <= XP is not able to connect to servers that no longer
-support the legacy handshakes and algorithms used by those versions. If you
-will be using curl in one of those earlier versions of Windows you should
-choose another SSL backend like OpenSSL.
