                     15:      _I-_x_r_e_f provides a cross-reference facility for Icon pro-
                     16:      grams. It lists the occurrences of each variable by line
                     17:      number. Variables are listed by procedure or separately as
                     18:      globals.  The options specify the formatting of the output
                     19:      and whether or not to cross-reference quoted strings and
                     20:      non-alphanumerics. Variables that are followed by a left
                     21:      parenthesis are listed with an asterisk following the name.
                     22:      If a file is not specified, then standard input is cross-
                     23:      referenced.
                     24: 
                     25:      The following options change the format defaults. They may
                     26:      appear in any order:
                     27: 
                     28:      ----cccc _n   The column width per line number. The default is 4
                     29:             columns wide.
                     30: 
                     31:      ----llll _n   The starting column (i.e. left margin) of the line
                     32:             numbers.  The default is column 40.
                     33: 
                     34:      ----wwww _n   The column width of the whole output line. The
                     35:             default is 80 columns wide.
                     36: 
                     37:      Normally only alphanumerics are cross-referenced. These
                     38:      options expand what is considered:
                     39: 
                     40:      ----qqqq     Include quoted strings.
                     41: 
                     42:      ----xxxx     Include all non-alphanumerics.
