- The C script is not complete; use at your own risk.
-
- Lessons are in
- /usr/lib/learn/*
- Source is in
- /usr/src/cmd/learn
- Miscellaneous supporting code is also in source.
-
- Make a learn by
- make
- When this seems right, extract the lessons by
- make lessons
- This extracts the lesson archives
- for each course. You can also do this one step at a
- time with "make files", "make editor", etc.,
- if you don't want all courses.
- If you do things separately, you must also say
- make play; make log
-
- Finally, check that it's sensible with
- make check
- If that doesn't print any messages,
- you're probably in good shape.
-
- Learn requires general write permission on the user playpen
- directory .../lib/play. Lesson directories may be protected.
-
- Learn collects a log file for each script in the .../lib/log
- directory, with a file for each script (files,
- editor, etc.) containing an entry for each lesson
- attempted. These files will grow without bound,
- unless they are periodically truncated.
- The log files should have general write permission.
- If you don't want logging (a sensible position to take),
- set the variable "logging" to zero in source/lrndef
- before making learn.
-
- Learn requires about 1500 blocks to make itself,
- and about 1000 when completely made.
-
- Please report problems, bad lessons, etc., to
- Brian Kernighan, MH 6021, 2C-518, or
- Mike Lesk, MH 6377, 2C-572. Thanks.
