Purpose

Command

安裝 Beta 版套件

$ brew info jython
jython: stable 2.5.3, devel 2.7-b1
...
$ brew install --devel jython

看看 brew install 的時候有哪些編譯選項可以用

brew info graphviz    # 版本資訊 / 相依套件 / 編譯選項
brew options graphviz # 只有編譯選項

移除沒在用的套件 (已經有安裝新版本，但是舊版還在)
注意!! 這個指令可能導致自編譯套件找不到 lib

brew cleanup
brew cleanup $FORMULA
brew cleanup -n # dry-run
