 SYNOPSIS
 ========
 
-cxrefbas **input-file**
+cxrefbas [**-v**] **input-file**
 
 DESCRIPTION
 ===========
 
 **cxrefbas** reads an Atari 8-bit BASIC tokenized program. For each
 line number in the program, it prints a list of lines that reference
-it, via *GOTO*, *GOSUB*, *RESTORE*, *TRAP*, *ON/GOTO*, *ON/GOTO*,
-or *ON/GOSUB*.
+it. Each reference is followed by a letter that indicates the type
+of reference:
+
+**G**
+  *GOTO* (without *ON*) or *GO TO*.
+
+**S**
+  *GOSUB* (without *ON*).
+
+**I**
+  *IF* with line number only, e.g. *IF X THEN 1000*.
+
+**O**
+  *ON/GOTO* or *ON/GOSUB*.
+
+**R**
+  *RESTORE*.
+
+**T**
+  *TRAP*.
 
 If a line doesn't exist, but is referenced (e.g. *GOTO 100*, but there
 is no line 100), it's printed in the table, prefixed with *!*.
