+=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 $dom-domainconfig user.
+
+domainprefs.pm in combination with lonconfigsettings.pm will retrieve and display
+the current settings, and provides an interface to make modifications.
+
+=head1 SUBROUTINES
+
+=over
+
+=item print_quotas()
+
+Inputs: 4
+
+$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 automatically 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.
