-// Package os provides a platform-independent interface to operating system
-// functionality. The design is Unix-like, although the error handling is
-// Go-like; failing calls return values of type error rather than error numbers.
-// Often, more information is available within the error. For example,
-// if a call that takes a file name fails, such as Open or Stat, the error
-// will include the failing file name when printed and will be of type
-// *PathError, which may be unpacked for more information.
-//
-// The os interface is intended to be uniform across all operating systems.
-// Features not generally available appear in the system-specific package syscall.
-//
-// Here is a simple example, opening a file and reading some of it.
-//
-//	file, err := os.Open("file.go") // For read access.
-//	if err != nil {
-//		log.Fatal(err)
-//	}
-//
-// If the open fails, the error string will be self-explanatory, like
-//
-//	open file.go: no such file or directory
-//
-// The file's data can then be read into a slice of bytes. Read and
-// Write take their byte counts from the length of the argument slice.
-//
-//	data := make([]byte, 100)
-//	count, err := file.Read(data)
-//	if err != nil {
-//		log.Fatal(err)
-//	}
-//	fmt.Printf("read %d bytes: %q\n", count, data[:count])
