B<%program%> will normally determine your current locale by a call to the C function B (3) which interrogates various environment variables, possibly including $B and $B. To temporarily override the determined value, use this option to supply a I string directly to B<%program%>. Note that it will not take effect until the search for pages actually begins. Output such as the help message will always be displayed in the initially determined locale.
