我使用斜纹布（0.9），我还想访问它的内置机械分布（在 Python 2.6.6 上）。我阅读了所有文档，但我不清楚他们是否支持或推荐，如果是，他们当然不会公开它。看来你可以这样做：
import _mechanize_dist as mechanize
br = mechanize.Browser()
br.open('http://www.yahoo.com')
但是mechanize 会在下面抛出愚蠢的 AttributeErrorrobotparser._debug。我不应该尝试使用它吗？还是只是机械化处理草率的异常？（斜纹布本身工作正常twill.commands.go('http://www.yahoo.com')：）
Traceback (most recent call last):

AttributeError: 'module' object has no attribute '_debug'
（最后一个问题是：我不知道并排使用 twill 和 mechanize 命令的任何警告？）
