目前 go doc 的功能少了很多 flag 只剩下這些
Flags:
-all
show all documentation for package
-c symbol matching honors case (paths not affected)
-cmd
show symbols with package docs even if package is a command
-src
show source code for symbol
-u show unexported symbols as well as exported
好像就沒辦法跑之前的 -http :6060
還是這個功能由別的工具處理?
