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
