脊骨矫正板

Again I reflected: I scarcely knew what school was: Bessie sometimes spoke of it as a place where young ladies sat in the stocks, wore backboards, and were expected to be exceedingly genteel and precise: John Reed hated his school, and abused his master; but John Reed's tastes were no rule for mine, and if Bessie's accounts of school-discipline (gathered from the young ladies of a family where she had lived before coming to Gateshead) were somewhat appalling, her details of certain accomplishments attained by these same young ladies were, I thought, equally attractive.

我再次沉思起来。我几乎不知道学校是什么样子。光听贝茜有时说起过，那个地方，年轻女子带足枷坐着，戴着脊骨矫正板，还非得要十分文雅和规矩才行。约翰·里德对学校恨之入骨，还大骂教师。不过他的感受不足为凭。如果贝茜关于校纪的说法（她来盖茨黑德之前，从她主人家一些年轻小姐那儿收集来的）有些骇人听闻，那么她细说的关于那些小姐所学得的才艺，我想也同样令人神往。

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。
