# Module twapiTlsPlus
#
# Temporary wrapper for package twapi, to expose the same API as package tls.
# - Command twapiTlsPlus::socket, cf. tls::socket, replacement for ::socket, for
# use with http::register.
# - Variable twapiTlsPlus::socketCmd, cf. tls::socketCmd, holds the value of the
# callback command used by twapi to open a socket.
#
# Intended to allow twapi TLS to use an https proxy server, and a background
# thread for evaluation of ::socket.
#
# For twapiTlsPlus to work correctly, twapi*/tls.tcl must be edited so that
#- set so [$socketcmd {*}$socket_args {*}$args]
#+ set so [{*}$socketcmd {*}$socket_args {*}$args]
