+dnl   MYSQL_CHECK_SSL
+dnl
+dnl Provides the following configure options:
+dnl --with-ssl=DIR
+dnl Possible DIR values are:
+dnl - no - the macro will disable use of ssl
+dnl - bundled, empty or not specified - means use ssl lib
+dnl   bundled along with MySQL sources
+dnl - ssl location prefix - given location prefix, the macro expects
+dnl   to find the header files in $prefix/include/, and libraries in
+dnl   $prefix/lib. If headers or libraries weren't found at $prefix, the
+dnl   macro bails out with error.
