# Proxy support for retrieving the current version of Tkcon.

#
# In your tkcon.cfg or .tkconrc file put your proxy details into the
# `proxy' member of the `PRIV' array. e.g.:
#
# set ::tkcon::PRIV(proxy) wwwproxy:8080
#
# If you want to be prompted for proxy authentication details (eg for
# an NT proxy server) make the second element of this variable non-nil - eg:
#
# set ::tkcon::PRIV(proxy) {wwwproxy:8080 1}
#
# Or you can set the above variable from within tkcon by calling
#
# tkcon master set ::tkcon:PRIV(proxy) wwwproxy:8080

##
## If you set ::tkcon::OPT(exec) to {}, then instead of a multiple
## interp model, you get tkcon operating in the main interp by default.
## This can be useful when attaching to programs that like to operate
## in the main interpter (for example, based on special wish'es).
## You can set this from the command line with -exec ""
## A side effect is that all tkcon command line args will be used
## by the first console only.
