/*
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. 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 and getgrnam_r.

When cgo is available, cgo-based (libc-backed) code is used by default.
This can be overridden by using osusergo build tag, which enforces
the pure Go implementation.
