		Package user allows user account lookups by name or id.
		
		For most Unix systems, this package has two internal implementations of
		resolving user and group ids to names, and listing supplementary group IDs.
		One is written in pure Go and parses /etc/passwd and /etc/group. The other
		is cgo-based and relies on the standard C library (libc) routines such as
		getpwuid_r, getgrnam_r, and getgrouplist.
		
		When cgo is available, and the required routines are implemented in libc
		for a particular platform, cgo-based (libc-backed) code is used.
		This can be overridden by using osusergo build tag, which enforces
		the pure Go implementation.

	 type User (struct)
		User represents a user account.

		Fields (total 5, all are exported)
			Gid string
				Gid is the primary group ID.
				On POSIX systems, this is a decimal number representing the gid.
				On Windows, this is a SID in a string format.
				On Plan 9, this is the contents of /dev/user.

			HomeDir string
				HomeDir is the path to the user's home directory (if they have one).

			Name string
				Name is the user's real or display name.
				It might be blank.
				On POSIX systems, this is the first (or only) entry in the GECOS field
				list.
				On Windows, this is the user's display name.
				On Plan 9, this is the contents of /dev/user.

			Uid string
				Uid is the user ID.
				On POSIX systems, this is a decimal number representing the uid.
				On Windows, this is a security identifier (SID) in a string format.
				On Plan 9, this is the contents of /dev/user.

			Username string
				Username is the login name.

		Methods (only one, which is exported)
			(*User) GroupIds() ([]string, error)

		changes to the current user.

	 func Lookup(username string) (*User, error)
		Lookup looks up a user by username. If the user cannot be found, the
		returned error is of type [UnknownUserError].

	 func LookupGroup(name string) (*Group, error)
		LookupGroup looks up a group by name. If the group cannot be found, the
		returned error is of type [UnknownGroupError].

	 func LookupGroupId(gid string) (*Group, error)
		LookupGroupId looks up a group by groupid. If the group cannot be found, the
