                      2: Where scantron exams are used in a course, the format of data in the
                      3: file generated from the processing of bubbled-in scantron sheets may
                      4: vary between institutions. The format definitions available when performing
                      5: scantron grading in LON-CAPA were originally listed in the scantronformat.tab
                      6: file, stored in /home/httpd/lonTabs, which might have been modified
                      7: locally on each server. 
                      8: 
                      9: Starting with LON-CAPA 2.7, scantron format information is read from
                     10: either a custom.tab file, or a default.tab file both of which belong
                     11: to the special domain configuration user (\$dom-domainconfig, where
                     12: \$dom is the name of the domain) and which are automatically published
                     13: into resource space. 
                     14: 
                     15: For LON-CAPA installations older than 2.7, when the primary library
                     16: server for the domain has been updated, a Domain Coordinator should
                     17: display the \char`\"{}Scantron format file\char`\"{} configuration
                     18: page via \char`\"{}Domain Configuration\char`\"{}. The first time
                     19: this page is displayed, a default.tab (a copy of the standard LON-CAPA
                     20: scantronformat.tab file), and a custom.tab (if the scantronform.tab
                     21: file currently on the server differs from the standard file) will
                     22: be copied and published. Thereafter any changes to scantron format
                     23: files to be used for grading scantron exams in courses from the domain
                     24: will be made via the Domain Configuration menu. Any scantronform.tab
                     25: files in /home/httpd/lonTab directories on servers in the domain will
                     26: no longer be used.
                     27: 
                     28: The settings available via \char`\"{}Scantron format file\char`\"{}
                     29: support upload of a new custom file, or deletion of an existing custom
                     30: file (in which case grading will default to use of the default.tab
                     31: file). An uploaded scantron format file contains one or more lines
                     32: of colon-separated values for the parameters in the following order:
