+=head1 NAME
+
+Apache::domainprefs.pm
+
+=head1 SYNOPSIS
+
+Handles configuration of a LON-CAPA domain.  
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+
+=head1 OVERVIEW
+
+Each institution using LON-CAPA will typically have a single domain designated 
+for use by individuals affliated with the institution.  Accordingly, each domain
+may define a default set of logos and a color scheme which can be used to "brand"
+the LON-CAPA instance. In addition, an institution will typically have a language
+and timezone which are used for the majority of courses.
+
+LON-CAPA provides a mechanism to display and modify these defaults, as well as a 
+host of other domain-wide settings which determine the types of functionality
+available to users and courses in the domain.
+
+There is also a mechanism to configure cataloging of courses in the domain, and
+controls on the operation of automated processes which govern such things as
+roster updates, user directory updates and processing of course requests.
+
+The domain coordination manual which is built dynamically on install/update of 
+LON-CAPA from the relevant help items provides more information about domain 
+configuration.
+
+Most of the domain settings are stored in the configuration.db GDBM file which is
+housed on the primary library server for the domain in /home/httpd/lonUsers/$dom,
+where $dom is the domain.  The configuration.db stores settings in a number of 
+frozen hashes of hashes.  In a few cases, domain information must be uploaded to
+the domain as files (e.g., image files for logos etc., or plain text files for
+bubblesheet formats).  In this case the domainprefs.pm must be running in a user
+session hosted on the primary library server in the domain, as these files are 
+stored in author space belonging to a special $dom-domainconfig user.   
+
+domainprefs.pm in combination with lonconfigsettings.pm will retrieve and display
+the current settings, and provides an interface to make modifications.
+
+=head1 SUBROUTINES

+=item print_quotas()
+
+Inputs: 4 
+
+$dom,$settings,$rowtotal,$action.
+
+$dom is the domain, $settings is a reference to a hash of current settings for
+the current context, $rowtotal is a reference to the scalar used to record the 
+number of rows displayed on the page, and $action is the context (either quotas 
+or requestcourses).
+
+The print_quotas routine was orginally created to display/store information
+about default quota sizes for portfolio spaces for the different types of 
+institutional affiliation in the domain (e.g., Faculty, Staff, Student etc.), 
+but is now also used to manage availability of user tools: 
+i.e., blogs, aboutme page, and portfolios, and the course request tool,
+used by course owners to request creation of a course.
+
+Outputs: 1
+
+$datatable  - HTML containing form elements which allow settings to be changed. 
+
+In the case of course requests, radio buttons are displayed for each institutional
+affiliate type (and also default, and _LC_adv) for each of the course types 
+(official, unofficial and community).  In each case the radio buttons allow the 
+selection of one of four values:
+
+0, approval, validate, autolimit=N (where N is blank, or a positive integer).
+which have the following effects:
+
+0
+
+=over
+
+- course requests are not allowed for this course types/affiliation
+
+=back
+
+approval 
+
+=over 
+
+- course requests must be approved by a Doman Coordinator in the 
+course's domain
+
+=back
+
+validate 
+
+=over
+
+- an institutional validation (e.g., check requestor is instructor
+of record) needs to be passed before the course will be created.  The required
+validation is in localenroll.pm on the primary library server for the course 
+domain.
+
+=back
+
+autolimit 
+
+=over
+ 
+- course requests will be processed autoatically up to a limit of
+N requests for the course type for the particular requestor.
+If N is undefined, there is no limit to the number of course requests
+which a course owner may submit and have processed automatically.
