  <DESCRIPTION>
- define handlers, set parameters
+ This file has two major functions.
+ For the Apache web server, it defines a global
+ access configuration which defines what server options (Indexes", "Includes",
+ "FollowSymLinks", "ExecCGI", or "MultiViews") are associated
+ with specific directories ("/", "/home/httpd/html", "/home/httpd/cgi-bin",
+ and "/usr/doc").  For the LON-CAPA network server and perl module
+ handlers, it defines machine specific settings (lonHostID, lonRole,
+ lonAdmEMail, lonDefDomain, lonLoadLim, lonExpire, and lonReceipt)
+ and internal machine settings for specific directories, socket ports,
+ and browser detection logic.

- access to construction area
+ This module provides access to an educational resource construction area.
+ This module is invoked by the URL-related pattern syntax

+ is coordinated through cookies (hence the abbreviation; "cacc" corresponds
+ to "cookie-based access").  If the cookie handle is invalid, then
+ this module returns a forbidden status and makes appropriate log entries.
+ If the cookie handle is valid, status is determined to be okay (and
+ the resource is delivered by the <TT>lonconstruct</TT> module).
