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 (defaults to "Google LLC")
-f custom license file (no default)
-l license type: apache, bsd, mit (defaults to "apache")
-y year (defaults to current year)
The pattern argument can be provided multiple times, and may also refer to single files.
