     Usage
     =====
 
+    Options (case sensitive):
+
+	-p	Enable the parent process (i.e. the command shell used to
+		run ANSICON) to recognise escapes.
+
+	-m	Set the current (and default) attribute to grey on black
+		("monochrome"), or the attribute following the `m' (please
+		use `COLOR /?' for attribute values).
+
+	-e	Echo the command line - the character after the `e' is
+		ignored, the remainder is displayed verbatim.
+
+	-E	As above, but no newline is added.
+
+	-t	Display ("type") each file (or standard input if none or the
+		name is "-") as though they are a single file.
+
+	-T	Display "==> FILE NAME <==", a blank line (or an error
+		message), the file and another blank line.
+
     Running ANSICON with no arguments will start a new instance of the com-
     mand processor (the program defined by the `ComSpec' environment var-
     iable, typically `CMD.EXE'), or display standard input if it is redir-
-    ected.  Passing the option `-p' (case sensitive) will enable the parent
+    ected.  Any argument will be treated as a program and its arguments.

-    `COLOR /?' for attribute values).  The option `-e' will echo the command
-    line - the character after the `e' is ignored, the remainder is display-

-    `-t' will display each file (or standard input if none or it is "-"), as
-    though they are a single file; `-T' will display the file name (in be-
-    tween "==> " and " <=="), a blank line (or an error message), the file
-    and another blank line.  Anything else will be treated as a program and
-    its arguments.  Eg: `ansicon -m30 -t file.ans' will display `file.ans'
