1:
2: Upgrading to CAPA 5.1
3:
4:
5: --------------------------------------------------------------------------------
6:
7: READ ALL INSTRUCTIONS BEFORE PRECEDING WITH THE INSTALLATION.
8:
9: Please go to http://capa.msu.edu/mailman and subscribe to the CAPA Announce
10: email list. Anyone interested in receiving CAPA updates and announcements
11: can add himself or herself to the list. Please notify all instructors and
12: technical staff that will work with CAPA about adding themselves to the list.
13:
14: The following installation instructions assume that whoever is upgrading
15: the CAPA system already has some knowledge of their operating system and
16: is familiar with Unix commands such as the following: cd, chown, chmod and
17: setting permissions, compress/uncompress, cp, ln, lpr, ls, mkdir, pwd, rm,
18: su, tar, and the vi editor.
19:
20: In order to complete the installation, you will need to have Perl,
21: Ghostscript, TeTex, and a webserver (e.g. Apache) installed on your machine
22: (all of which can be obtained for free). You should know where those
23: applications are located and where the web server's configuration files are
24: located (particularly srm.conf). You should also be familiar with killing
25: and restarting your web daemon.
26:
27: You will notice lists of files in these instructions to compare your
28: permissions with. Depending on your operating system, many of your file
29: sizes may differ with the ones given in these instructions. Please do
30: not be concerned by this.
31:
32: --------------------------------------------------------------------------------
33:
34: SETTING UP THE INSTRUCTOR INTERFACE AND OPTIONAL TELNET STUDENT INTERFACE
35:
36: You have the option to install the telnet version of the CAPA interface.
37: It responds much quicker than the web, especially with a slow modem. If
38: you decide not to enable this feature then skip steps 5 and 6.
39:
40: Please note that in the following instructions, it is assumed that the
41: teacher directory is in /home. This may not be the case with your machine
42: (e.g. /usr/users, /home2, etc.). You may want to make note of this as you
43: read through these instructions prior to installation.
44:
45: 1.) Become root and copy or move the DIST51 directory to the teacher home
46: directory. Recursively change the ownership of the DIST51 directory to
47: teacher with group membership cai.
48:
49: >chown -R teacher:cai DIST51
50:
51: 2.) We first need to link up the binaries to use the instructor
52: interface of CAPA. Login as root. Change directory to /usr/local/bin
53: (or /usr/bin, or whatever will be the default in your users "path").
54: Remove all the old links to the CAPA 5.0 binaries and then symbolically
55: link the 5.1 binaries contained with the distribution by entering the
56: following commands:
57:
58: > cd /usr/local/bin
59: > ln -s /home/teacher/DIST51/LinkToBin/quizzer .
60: > ln -s /home/teacher/DIST51/LinkToBin/grader .
61: > ln -s /home/teacher/DIST51/LinkToBin/manager .
62: > ln -s /home/teacher/DIST51/LinkToBin/qzparse .
63: > ln -s /home/teacher/DIST51/LinkToBin/allcapaid .
64: > ln -s /home/teacher/DIST51/LinkToBin/answers .
65:
66: 3.) Check that all of the binaries in /home/teacher/DIST51/LinkToBin
67: have executable permissions as shown below:
68:
69: >cd /home teacher/DIST51/LinkToBin
70: >ls -l
71: -rwxr-xr-x 1 teacher cai 485095 Jul 17 14:35 allcapaid
72: -rwxr-xr-x 1 teacher cai 505454 Jul 17 14:35 answers
73: -rwxr-xr-x 1 teacher cai 2126685 Jul 17 14:35 grader
74: -rwxr-xr-x 1 teacher cai 2267429 Jul 17 14:35 manager
75: -rwxr-xr-x 1 teacher cai 2191991 Jul 17 14:35 quizzer
76: -rwxr-xr-x 1 teacher cai 488366 Jul 17 14:35 qzparse
77:
78: 4.) Now link up the demonstration library in the root directory. To do this,
79: login as root, change to the root directory (cd /), remove the old demolibrary
80: link (rm demolibrary), and enter:
81:
82: > ln -s /home/teacher/DIST51/demolibrary demolibrary
83:
84: Check that the demolibrary in the DIST51 folder is owned by "teacher" and
85: has group membership "cai".
86:
87: 5.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
88: Login as "teacher" and copy the file "capalogin" from the directory
89: DIST51/PutInCAPA51 into the directory /home/teacher/CAPA51. Check
90: to make sure your permissions match the following:
91:
92: -rwsr-xr-x 1 teacher cai 585097 Jul 17 15:03 capalogin
93:
94: Make certain that capalogin is set UID mode (there is an "s" instead
95: of an "x" in the user's permissions). If not enter the following:
96:
97: > chmod u+s capalogin
98:
99: 6.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
100: For each class that telnet is enabled for, it is added as a user
101: to the system without a password. The security of the system is
102: maintained by using capalogin as the login shell. To set up the
103: demonstration class, become root then use the adduser utility to create the
104: user "nsc131s0". Enter the group id the same as the instructor (cai), the
105: home directory to be /home/teacher/CAPA51/nsc131s0, and the login shell
106: to be /home/teacher/CAPA51/capalogin. When you are prompted to
107: enter an initial password, hit return. You then need to edit the
108: /etc/passwd file with the vipw command to remove the "Nologin" field.
109: (You may also need to edit the file /etc/shadow if your system uses
110: shadow passwords.)
111:
112: For Linux systems, you will need to create the user, edit /etc/passwd
113: to remove the password field, change the group id number, change the home
114: directory and change the login shell. You will not be prompted for these
115: within the utility. Make certain the group id number is the same as the
116: instructor account. Editing the passwd file is done by becoming root
117: using the vipw command. (You may also need to edit the file /etc/shadow
118: if your system uses shadow passwords.) Finally, you must delete the
119: directory created by the adduser utility, for example:
120:
121: >rm -rf /home/nsc131s0
122:
123: Depending on your system, you may not be allowed to add a user without a
124: password using the adduser utility. If this is the case, you will need
125: to manually add the user with the vipw command.
126:
127: Repeat the steps above for qns131s0 and xpc131s0 (do not add xns131s0 as
128: a user).
129:
130: The correct class entries in /etc/passwd are given below: (The paths to the
131: home directory and login shell may differ for your system.)
132:
133: nsc131s0::1004:103:Demonstration Class - Homework:/home/teacher/CAPA51/nsc131s0:
134: /home/teacher/CAPA51/capalogin
135: qns131s0::1005:103:Demonstration Class - Quizzes:/home/teacher/CAPA51/qsc131s0:/
136: home/teacher/CAPA51/capalogin
137: xpc131s0::1006:103:Demonstration Class - Exam Partial Credit:/home/teacher/CAPA5
138: 1/xpc131s0:/home/teacher/CAPA51/capalogin
139:
140: 7.) Login as teacher and create the class called nsc131s0 in teacher's
141: CAPA51 directory by copying this directory from DIST51/PutInCAPA51
142:
143: > cd CAPA51
144: > cp -R /home/teacher/DIST51/PutInCAPA51/nsc131s0 nsc131s0
145:
146: Then, check to be certain the owner of the nsc131s0 directory is "teacher"
147: with group membership "cai".
148:
149: Repeat this step using the qns131s0, xns131s0, and xpc131s0 directories.
150:
151: 8.) Make certain a directory named "records" exists in each of the class
152: directories (e.g. /home/teacher/CAPA51/nsc131s0/records). Also, make certain the
153: ownership of all sub-directories and files is "teacher" with group membership
154: "cai". It is a good idea to check your permission with the ones below.

232: 9.) The CAPA system needs to access the files just installed in the teacher
233: home directory. Make sure this directory has both group and world r-x
234: privledges.
235:
236: drwxr-xr-x 6 teacher cai 1024 Jul 17 13:43 teacher
237:
238:
239:
240: You will have similar files in the qns131s0, xns131s0, and xpc131s0 directories
241: with the same permissions. Check those also.
242:
243: The utilities for running CAPA with telnet sessions are now completely
244: installed.
245:
246: --------------------------------------------------------------------------------
247: SETTING UP THE WEB VERSION OF THE CAPA INTERFACE
248:
249:
250: 1.) It is recommended that you make a backup of the teacher/PublicWeb
251: directory and all of it's subdirectories and files before making the
252: changes below.
253:
254: 2.) Login in as teacher. Remember, it is assumed that the teacher
255: directory is in /home which may not be the case for your machine.
256:
257: 3.) Update your /home/teacher/PublicWeb/CAPA directory with the files from
258: DIST51/CopyToPublicWeb/CAPA directory.
259:
260: Go to /home/teacher/PublicWeb/CAPA and copy ExmPanel.class, ExpPanel.class,
261: GLabel.class, TScore.class, help.html from the distribution. Make sure the old
262: files for Glabel.class and help.html are replaced (they will have today's date
263: when you check permissions). Make sure all files in this directory are owned by
264: teacher and have group membership cai.
265:
266: > cd /home/teacher/PublicWeb/CAPA
267: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/ExmPanel.class .
268: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/ExpPanel.class .
269: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/GLabel.class .
270: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/TScore.class .
271: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/help.html .
272:
273: 4.) Update your /home/teacher/PublicWeb/CAPA/capa-bin directory with the files
274: from DIST51/CopyToPublicWeb/CAPA/capa-bin directory. Particularly, you will need
275: to update web.settings, capadiscuss_html, capahtml, and webpage.
276:
277: > cd capa-bin
278: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/web.settings .
279: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/capadiscuss_html .
280: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/capahtml .
281: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/webpage .
282:
283: 5.) Check permissions in the capa-bin directory. Your permissions for the files
284: in PublicWeb/CAPA/capa-bin should like the following:
285:
286: > cd capa-bin
287: > ls -l
288: -rw-r--r-- 1 teacher cai 33363 Jul 17 15:51 capadiscuss_html
289: -rws--x--x 1 teacher cai 519680 Jul 17 15:51 capahtml
290: -rw-r--r-- 1 teacher cai 223 Jul 17 15:51 class.conf
291: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 class.html -> webpage
292: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 email.html -> webpage
293: lrwxrwxrwx 1 teacher cai 7 Jul 17 15:51 getid.html -> webpage
294: drwxr-xr-x 2 teacher cai 1024 Jul 17 15:51 teacher
295: -rw-r--r-- 1 teacher cai 4460 Jul 17 15:51 web.settings
296: -rws--x--x 1 teacher cai 1141535 Jul 17 15:51 webpage
297:
298: If your permissions do not match the ones above, change them so they do.
299:
300: > chmod u+s capahtml
301: > chmod u+s webpage
302:
303: You may also see files called web_access.log and ids.log in the capa-bin
304: directory. These files are automatically generated by the CAPA software.
305:
306: 6.) The system links to the webpage program should still be there from the
307: previous CAPA installation. If they do not exist, enter the following:
308:
309: > ln -s webpage class.html
310: > ln -s webpage emailid.html
311: > ln -s webpage getid.html
312:
313: 7.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/web.settings
314: Change the first line:
315: set machine capa2.nscl.msu.edu
316: To read:
317: set machine your.machine.name
318:
319: 8.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/class.conf by adding
320: the following lines (note that you may have different paths than
321: /home/teacher):
322:
323: nsc131s0 /home/teacher/CAPA51 teacher {class emailid}
324: qns131s0 /home/teacher/CAPA51 teacher {class}
325: xpc131s0 /home/teacher/CAPA51 teacher {class}
326:
327: 9.) Update your /home/teacher/PublicWeb/CAPA/capa-bin/teacher directory with the
328: files from DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher directory. Copy the files
329: capasbin and capadiscuss to this directory from distribution.
330:
331: > cd teacher
332: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capasbin .
333: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capadiscuss .
334:
335: Check that both these files are owned by teacher and have group membership cai.
336: These files should also have executable permission and capasbin should be set
337: UID (there is an "s" instead of an "x" in the owner's permissions). If not,
338: enter the following:
339:
340: > chmod u+s capasbin
341:
342: 10.) Make the changes that you made above for the teacher directory to all
343: other instructor directories. Make sure they are owned by the appropriate
344: instructor and have the appropriate group membership.
345:
346: 11.) Go to /home/teacher/Public/demolibrary and make sure Graphics and Links
347: point to /demolibrary/Graphics and /demolibrary/Links. If they point to the old
348: demolibrary, make changes by removing the links and adding the new ones.
349:
350: > ln -s /demolibrary/Graphics Graphics
351: > ln -s /demolibrary/Links Links
352:
353: 12.) Restart your webserver.
354:
355:
356: --------------------------------------------------------------------------------
357:
358: FINAL INSTRUCTIONS
359:
360: 1.) Modify /demolibrary/Tools/StdMacros
361:
362: Replace the line
363: /LET machine_name="capa2.nscl.msu.edu" // needed for labeling tools
364: With
365: /LET machine_name="your.machine.name" // needed for labeling tools
366:
367: 2.) Double check to be certain the ownership and group membership
368: for each of the files and subdirectories under the teacher account
369: consistently have "teacher" as owner and "cai" as group. Also double
370: check that the demolibrary directory in /home/teacher/DIST51 is owned
371: by "teacher" and has group membership "cai". (Note that your instructor
372: directories under PublicWeb/CAPA/capa-bin will be owned my the appropriate
373: instructory).
374:
375: 3.) Make sure that the user teacher, the owner of the webserver, and
376: root have the commands allcapaid, perl and gs (ghostscript command) in
377: their path. You can check this by using the which command. If it is
378: in the user's path, you will then be shown where the directory for the
379: command is located.
380: For example:
381:
382: > which perl
383: /usr/bin/perl
384:
385: 4.) If teacher is somewhere other than /home, then you need to edit the
386: capa.config files in the nsc131s0, qns131s0, xns131s0, and xpc131s0 directories.
387: Change the following lines to refer to the correct path:
388:
389: quiz_path = /home/teacher/CAPA51/qns131s0
390: exam_path = /home/teacher/CAPA51/xns131s0
391: supp_path = /home/teacher/CAPA51/xpc131s0
392: .
393: .
394: .
395: correction_path = /home/teacher/CAPA51/xpc131s0
396:
397: 5.) In each of the capa.config files (DIST51/PutInCAPA51/nsc131s0/capa.config,
398: ..., ...skeleton/capa.config, etc. and /home/teacher/CAPA51/nsc131s0, etc.) edit
399: the print commands to match the ones that you use from your server where CAPA is
400: installed. The comments in the printing configuration section of the capa.config
401: file will direct you how to make these changes.
402:
403: Also, edit the line:
404:
405: capa_server = your.machine.name
406:
407: In the "Extrapolate Scores Applet" section to read the name of your capa server
408: in each of the capa.config files.
409:
410: 6.) Print the Manual.
411:
412: 7.) Take a look at the sets in nsc131s0. In particular sets 3-17 (a
413: detailed list of the templates).
414:
415: 8.) Read the READMEsecurity.txt file.

435:
436: ADDING ADDITIONAL USERS
437:
438: 1.) Add the new user to your system with group membership cai. If you are
439: unsure about doing this, follow the same instructions outlined in the
440: "INITIAL SETUP" section of the README.txt file except use the new user's name
441: instead of "teacher" (and the new group's name if the new instructor to be added
442: to the CAPA system should be in a different group other than "cai").
443:
444: 2.) Login as root and add a directory to the capa-bin directory with the same
445: name as the new instructor's user name. For example:
446: > mkdir /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
447:
448: 3.) Copy the files capasbin and capadiscuss from
449: teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher into the new
450: instructor-name directory. For example:
451:
452: > cd /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
453: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capasbin .
454: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capadiscuss .
455:
456: Make sure that the permissions for the the capasbin and capadiscuss files
457: are executable and that capasbin is set UID mode (there is an "s" instead
458: of an "x" in the user's permissions). If not, enter the following:
459:
460: > chmod 755 capasbin capadiscuss
461: > chmod u+s capasbin
462: > ls -l
463: -rwxr-xr-x 1 instructor cai 23453 Mar 16 11:15 capadiscuss
464: -rwsr-xr-x 1 instructor cai 843150 Mar 16 11:15 capasbin
465:
466: 4.) Change the ownership of the instructor-name directory and all of its
467: files to the appropriate user ("instructor-name") and group (i.e. "cai").
468: > cd /home/teacher/PublicWeb/CAPA/capa-bin
469: > chown -R instructor-name:cai instructor-name
470:
471: 5.) Finally, double check that the instructor owns his/her directory
472: in the capa-bin directory and that the instructor's capasbin and capadiscuss
473: have the correct ownership and permissions.
474:
475: --------------------------------------------------------------------------------
476:
477: ADDING ADDITIONAL CLASSES
478:
479: Once an instructor account is created, you can add classes to the
480: system as needed. Below we call the owner of the class "instructor"
481: and the class "classname". Your class's name should be 8 characters
482: max if you will be using the telnet interface. We name our classes
483: names such as phy183s0 (physics 183, spring semester, 2000) and cem142f0
484: (chemistry 142, fall semester, 2000).
485:
486: If you chose not to enable the telnet interface, then skip steps
487: 1 and 2 below.
488:
489: 1.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
490: Use the adduser utility to create the user "classname". For Digital
491: Unix and Solaris operating systems:
492: a.) Login as root
493: b.) Change directory to /usr/sbin
494: c.) Type the command "adduser". You will be prompted for information.
495: -Make certain the user "classname" is a member of the same
496: group as the instructor.
497: -Use /home/instructor/CAPA51 as the parent directory and
498: /home/instructor/CAPA51/capalogin as the login shell.
499: -Do not add a password.
500: d.) Remove the system created classname directory. (Your absolute
501: path may differ from /home.)
502: >rm -rf /home/instructor/CAPA51/classname
503:
504: For Linux operating systems:
505: a.) Login as root
506: b.) change directory to /usr/sbin
507: c.) Type the command "adduser classname".
508: (or "useradd classname" depending on your system)
509: d.) If prompted for a password, do not add one.
510: e.) Delete the directory created by the adduser utility. (Your absolute
511: path may differ from /home.)
512: >rm -rf /home/classname
513: NOTE: Depending on your system, you may not be allowed to add a user
514: without a password. In that case, you will have to add the user
515: manually using the vipw command.
516:
517: 2.) *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
518: Edit the password file. For Digital Unix and Solaris operating systems:
519: a.) Edit the entry for "classname" in the /etc/passwd file with the vipw
520: command.
521: -remove the encrypted password field (or the field "NoLogin").
522: (You may need to also edit the /etc/shadow file if using
523: shadow passwords.)
524: -Check to be certain the home directory and login shell are
525: correct.
526: b.) A sample /etc/passwd entry is given below:
527:
528: phy123s0::1007:103:Intro Physics I:/home/instructor/CAPA51/phy123s0:/home/instru
529: ctor/CAPA51/capalogin
530:
531: For Linux operating systems:
532: a.) Edit the entry for "classname" in the /etc/passwd file.
533: -Remove the encrypted password field (or the field "NoLogin").
534: (You may need to also edit the /etc/shadow file if using
535: shadow passwords.)
536: -Change the group id number to match the group id number in
537: the instructor's account
538: -Change the home directory to
539: /home/instructor/CAPA51
540: -Change the login shell to
541: /home/instructor/CAPA51/capalogin
542: b.) A sample /etc/passwd entry is given below:
543:
544: phy123s0::1007:103:Intro Physics I:/home/instructor/CAPA51/phy123s0:/home/instru
545: ctor/CAPA51/capalogin
546:
547: 3.) Make the classname directory. Login as the "classname" owner, copy
548: the contents of /home/teacher/DIST51/PutInCAPA/skeleton into the new class
549: directory.
550: > cd /home/instructor/CAPA51
551: > cp -R /home/teacher/DIST51/PutInCAPA51/skeleton classname
552:
553: Make certain there is a classname/records directory present.
554: The following are a few files you might want to edit to tailor to your
555: particular course:
556:
557: welcome.msg and goodbye.msg (both for telnet), capa.config, HWTop, (QuizTop,
558: ExamTop), and classl
559:
560: Be certain to retain the exact character spacing in the classl file.
561:
562: 4.) Check to be certain the owner of the /home/instructor/CAPA51/classname
563: directory, sub-directories and files is "instructor" with group membership
564: "cai" (or whatever the correct group is).
565:
566: 5.) Once you have created your problem sets, your course is ready for
567: telnet access. That is, if you chose to enable the telnet interface.
568:
569: ------------------------------------------
570:
571: Setting up WWW access for this same course:
572:
573: 1.) Edit /home/teacher/PublicWeb/CAPA/capa-bin/class.conf by
574: adding the new class. Example:
575:
576: classname /home/instructor/CAPA51 instructor {class getid emailid}
577:
578: 2.) Make certain a copy of capa.config exists in the "classname"
579: directory. Also double check the ownership and group membership of
580: the classname file and all of its sub-directories and files have the
581: appropriate owner and group membership.
582:
583: 3.) The instructions above were for using CAPA for homework. If you
584: want to use CAPA for quizzes, exams, etc. then read the next section.
585:
586: 4.) Edit the paths and printing configuration section in the capa.config
587: file. Edit the dept_name, etc in the HWTop (QuizTop and ExamTop). Also
588: edit the classl file, making sure the instructor and TAs all belong to
589: the admin_section(s) (see capa.config file and edit admin_section if
590: appropriate).
591:
592: Your "classname" class is now ready to use for homework.
593:
594: --------------------------------------------------------------------------------
595:
596: ADDING ACCESS FOR QUIZZES, EXAMS, EXAM PARTIAL CREDIT, ETC.
597:
598: 1.) Quiz, exam, and other access are added as separate "classes".
599: You may choose to name them similar to the convention of the
600: demonstration "classes" nsc131s0 (homework), qns131s0 (quizzes),
601: xns131s0 (exams), and xpc131s0 (exam partial credit).
602:
603: 2.) To use CAPA for more than just homework, install your quiz,
604: exam, etc. directories using the instructions above but use the
605: appropriate skeleton directory (skeletonQuiz, skeletonExam). For
606: supplementary course work, such as exam partial credit, then just
607: use the skeleton directory. Follow the guidelines below when
608: setting up web access in the class.conf file.
609:
610: 2.) Below are some guidelines assuming you are using the entirety
611: of CAPA by adding quiz, exam, partial credit (supplemental), and other
612: access for a physics class PHY 123:
613:
614: qph123s0: Enable telnet if you do so and allow class.html
615: access only. This gives you the option of giving
616: take-home quizzes, but the students cannot use
617: emailid.html or getid.html, they must get their
618: CAPA ID in class. In the capa.config file, you
619: would enter the following:
620:
621: qph123s0 /home/instructor/CAPA51 instructor {class}
622:
623: xph123s0: Do not enable access through telnet or web interface.
624: If you do want telnet or web access, please be careful
625: to protect you exams by setting the correct open and
626: due dates and it is highly recommended that you do
627: NOT allow the students to retrieve their ID for further
628: protection. Consult the Manual about due dates.
629:
630: xpc123s0: You have the option in CAPA to allow students to take
631: the exam again at home and apply those points to their
632: exam score as partial credit. Set up similiar to quizzes
633: and BE CAREFUL about open dates and due dates to protect
634: your exam.
635:
636: oph123s0: Use this for whatever you wish, such as supplemental homework.
637:
638: 3.) Edit the paths in the capa.config file in each of the classname
639: directories. Edit the dept_name, etc. in the HWTop (QuizTop and ExamTop).
640: Also edit the classl file, making sure the instructor and TAs all belong to the
641: admin_section(s) (see capa.config file and edit admin_section if appropriate).
