vio/docs/README

-Virtual IO library.
-IO wrappers for sockets, fd-s, SSL.
-Languages:C++
-
-This library is based on work of many others.
-They have different policies and I haven't thought up
-about resulting licence - GPL, L(essen)GPL, BSD-style, whatever.
-The licences are here for reference:
-COPYING.mysql:	MySQL licence. Some socket functions.
-COPYING.dbug:	Fred Fish's dbug library. I use it extensively ;=)
-COPYING.openssl:OpenSSL licence. SSL wrappers.
-
-At the moment there is no real 'Makefile', just config.mk/targets.mk
-and Makefile.am to build it as a module in MySQL. Therefore, there
-is currently no possibility to build it as a separate library, but
-with MySQL-s root Makefile it should just a matter of leaving
-everything else out.
