+      (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.")
