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.
go get -u github.com/google/addlicense
addlicense [flags] pattern [pattern ...]
-c copyright holder (default "Google LLC.")
-l license type: apache, bsd, mit (default "apache")
-y year (default 2016)
The pattern argument can be provided multiple times, and may also refer to single files.
