19: .SH DESCRIPTION
20: .I Learn
21: gives CAI courses and practice in the use of UNIX.
22: To get started
23: simply type `learn'.
24: The program will ask questions to find out what
25: you want to do.
26: The questions may be bypassed by naming a
27: .I subject,
28: and the last
29: .I lesson
30: number that
31: .I learn
32: told you in the previous session.
33: You may also include a
34: .I speed
35: number that was given with the lesson number
36: (but without the parentheses that
37: .I learn
38: places around the speed number).
39: If
40: .I lesson
41: is
42: .LR - ,
43: .I learn
44: prompts for each lesson;
45: this is useful for debugging.

59: The special command
60: .L bye
61: terminates a
62: .I learn
63: session.
64: .PP
65: The
66: .BI - directory
67: option allows one to exercise a script in
68: a nonstandard place.

71: .SH BUGS
72: The main strength of
73: .I learn,
74: that it asks the student to use the real
75: UNIX, also makes possible baffling mistakes.
76: It is helpful, especially for nonprogrammers,
77: to have a UNIX initiate near at hand during the first
78: sessions.
79: .PP
80: Occasionally lessons are incorrect, sometimes because the local version
81: of a command operates in a non-standard way.
82: Such lessons may be skipped,
83: but it takes some sophistication to recognize
84: the situation.
