YET ANOTHER CONFIG CHANGE -- PLEASE READ. This chagne allows command-line scripts to continue to work without defining a bunch of environment variables. Hopefully this will be the last change... Now only $webwork_dir is set in webwork.apache-config. That file then uses this value to read the course environment and get the rest of the configuration values that it needs out of global.conf. global.conf now has variables like $webwork_url, $pg_dir, etc. at the top. In summary: * In httpd.conf, include webwork.apache-config. * In webwork.apache-config set $webwork_dir to the path to webwork2. * In global.conf, set $webwork_url, $pg_dir, $webwork_htdocs_url, $webwork_htdocs_dir, $webwork_courses_url, and $webwork_courses_dir.
