(synopsis "Go library for detecting and expanding the user's home directory without cgo")
(description "This is a Go library for detecting the user's home
directory without the use of @command{cgo}, so the library can be used in
cross-compilation environments.
Usage is simple, just call homedir.Dir() to get the home directory for a user,
and homedir.Expand() to expand the @command{~} in a path to the home
directory.
Why not just use @command{os/user}? The built-in @command{os/user} package
requires cgo on Darwin systems. This means that any Go code that uses that
package cannot cross compile. But 99% of the time the use for
@command{os/user} is just to retrieve the home directory, which we can do for
the current user without cgo. This library does that, enabling
cross-compilation.")
