Usage

goprune abs_path_of_main_or_lib.go ...

Below steps will be applied:

1. Find closest root dir of the go project with a go.mod file.
2. Set base to go module path defined in module field of go.mod.
3. Start from abs_path_of_main_or_lib.go, parse all imported packages that start with base.
4. Loop step 3 with imported packages until no files left.
5. Remove all go source files that have not been walked (not used).

With DRY_RUN=1 environment variable been set, will print removed files but not do the removal in step 5. With NO_TEST=1 environment variable been set, will also remove go test files in step 5.
