帮助信息为：

$ addlicense -h
Usage: addlicense [flags] pattern [pattern ...]

The program ensures source code files have copyright license headers
by scanning directory patterns recursively.

It modifies all source files in place and avoids adding a license header
to any file that already has one.

The pattern argument can be provided multiple times, and may also refer
to single files.

Flags:

      --check                check only mode: verify presence of license headers and exit with non-zero code if missing
  -h, --help                 show this help message
  -c, --holder string        copyright holder (default "Google LLC")
  -l, --license string       license type: apache, bsd, mit, mpl (default "apache")
  -f, --licensef string      custom license file (no default)
      --skip-dirs strings    regexps of directories to skip
      --skip-files strings   regexps of files to skip
  -v, --verbose              verbose mode: print the name of the files that are modified
  -y, --year string          copyright year(s) (default "2021")

参数说明：

• --check 只检查
• -f, --licensef 指定版权头文件
• -v 打印被更改的文件
• --skip-dirs 跳过指定的文件夹
