// reading coverage data files in a structured way. Clients create a
// CovDataReader to process a given collection of coverage data file
// directories, then pass in a visitor object with methods that get
// invoked at various important points. CovDataReader is intended
// to facilitate common coverage data file operations such as
// merging or intersecting data files, analyzing data files, or
// dumping data files.

//
// Usage:
//
//	go run addmod.go path@version...
//
// It should only be used for very small modules - we do not want to check
// very large files into testdata/mod.
//
// It is acceptable to edit the archive afterward to remove or shorten files.
// See mod/README for more information.

Init accepts one optional argument, the module path for the new module. If the
module path argument is omitted, init will attempt to infer the module path
using import comments in .go files, vendoring tool configuration files (like
Gopkg.lock), and the current directory (if in GOPATH).
