tcl-8.5 package 自动升级下载

teacup是tcl 8.5中新加的自动升级tclilib的工具，如果需要让它穿越代理 需要进行如下设置。

1 设置环境变量

set http_proxy_user=coolfire
set http_proxy_pass=******
teacup proxy 10.19.0.7 80

2 进入teacup目录（e.g. d:\Tcl\bin） teacup install tcom升级即可

下面是个操作例子：

D:\Tcl\bin>set http_proxy_user=coolfire

D:\Tcl\bin>set http_proxy_pass=****

D:\Tcl\bin>teacup proxy 10.19.0.7 80
