 .Sh DESCRIPTION
 The
-.Nm localedef
+.Nm
 utility converts source definitions for locale categories
 into a format usable by the functions and utilities whose operational behavior
 is determined by the setting of the locale environment variables; see
-.Xr environ 5 .
+.Xr environ 7 .

 The utility reads source definitions for one or more locale categories
-belonging to the same locale from the file named in the \fB-i\fR option (if
-specified) or from standard input.
+belonging to the same locale from the file named in the

 Each category source definition is identified by the corresponding environment
 variable name and terminated by an

-statement. The following categories are supported:
-.Bl -tag -width LC_MONETARY
-.It LC_CTYPE
+statement.
+The following categories are supported:

+.It Ev LC_CTYPE
 Defines character classification and case conversion.
-.It LC_COLLATE

 Defines collation rules.
-.It LC_MONETARY

+.It Fl f Ar charmap
+Specifies the pathname of a file containing a mapping of character symbols and
+collating element symbols to actual character encodings.
+This option must be specified if symbolic names (other than collating symbols
+defined in a

+keyword) are used.
+If the

+.It Fl i Ar sourcefile
+The path name of a file containing the source definitions.

+Specifies the name of a codeset used as the target mapping of character symbols
+and collating element symbols whose encoding values are defined in terms of the
+ISO/IEC 10646-1:2000 standard position constant values.
+See
+.Sx NOTES .
+.It Fl U
 Ignore the presence of character symbols that have no matching character
 definition.  This facilitates the use of a common locale definition file
 to be used across multiple encodings, even when some symbols are not
 present in a given encoding.

+Emit verbose debugging output on standard output.
+.It Fl w Ar widthfile
 The path name of the file containing character screen width definitions.
 If not supplied, then default screen widths will be assumed, which will
 generally not account for East Asian encodings requiring more than a single
 character cell to display, nor for combining or accent marks that occupy
 no additional screen width.
-.It -i sourcefile
-The path name of a file containing the source definitions. If this option is
-not present, source definitions will be read from standard input.
-.It -u codeset
-Specifies the name of a codeset used as the target mapping of character symbols
