# "Makefile.in" then it is a template for a Makefile;  to generate the
# actual Makefile, run "./configure", which is a configuration script
# generated by the "autoconf" program (constructs like "@foo@" will get

TLS (aka SSL) Channel - can be layered on any bi-directional Tcl_Channel.

Both client and server-side sockets are possible, and this code should work
on any platform as it uses a generic mechanism for layering on SSL and Tcl.

Full filevent sematics should also be intact - see tests directory for
blocking and non-blocking examples.
