Each project is publicly identified by a master URL. The URL cannot change, so choose it carefully. The master page at this URL has two functions.

It is the home page of the project; when viewed in a browser it describes the project and contains links for registering and for downloading the core client.
It contains XML elements of the form
```
";
echo htmlspecialchars("
http://host.domain.edu/cgi/scheduler
http://host2.domain.edu/cgi/scheduler
");
echo"
```
that give the URLs of the project's scheduling servers. These tags can be embedded within HTML comments. The BOINC core client reads and parses the master page to locate scheduling servers. If at any point it is unable to connect to any scheduling server for a project, it rereads the master page. This mechanism lets a project change the locations of its scheduling servers, or add new servers.
