+.Nd get locale-specific information
+.Sh SYNOPSIS
+.Nm
+.Op Fl a | Fl m
+.Nm
+.Op Fl ck
+.Op Ar keyword ...
+.Sh DESCRIPTION
+The
+.Nm
+utility is supposed to provide most locale specific information to
+the standard output.
+.Pp
+When
+.Nm
+is invoked without arguments it will print out a summary of the
+current locale environment depending on environment variable settings
+and internal status.
+.Pp
+When
+.Nm
+is invoked with arguments and no options specified it will print out
+.Em keyword Ns No 's
+value determined using current locale settings.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a
+Write names of all available locales.
+While looking for locales
+.Nm
+will respect the
+.Ev PATH_LOCALE
+environment variable, and use it instead of the system default
+locale directory.
+.It Fl c
+Write the category name for the selected keywords.
+.It Fl k
+Write the name and value of the selected keywords.
+.It Fl m
+Write names of all available charmaps.
+.El
+.Sh IMPLEMENTATION DETAILS
+Special
+.Pf ( Fx Ns -
+/
+.Nx Ns -specific )
+keyword
+.Ar list
+can be used to retrieve a human readable list of available keywords.
+.Sh DIAGNOSTICS
+.Ex -std locale
+.Sh STANDARDS
+.Nm
+conforms to
+.St -p1003.1-2001 .
+.Sh HISTORY
+.Nm
+first appeared in
+.Nx 2.0 .
+.Sh AUTHORS
+This implementation of
+.Nm
+was originally written by
+.An Alexey Zelkin
+.Aq phantom@FreeBSD.org
+for
+.Fx .
+.Sh BUGS
+Since
+.Nx
+does not support
+.Em charmap Ns No s
+in their
+.Em POSIX
+meaning
+.Nm
+emulates the
+.Fl m
+option via CODESETs listing of all available locales.
