is most useful with the
107 
.Li #!
108 
construct. The only difference between
109 
.Li "#! /usr/local/bin/foo"
110 
and
111 
.Li "#! /usr/bin/env /usr/local/bin/foo"
112 
is that the latter works even if
113 
.Pa /usr/local/bin/foo
114 
is itself scripted. The facilities of env allow reference to
115 
.Ic foo
116 
without the path,
117 
and allow the script author to set up environment variables as needed.
