+SYNOPSIS
+	void preload(string file)
+
+DESCRIPTION
+	Load the object with the given file name, that was returned by
+	epilog(). It is task of the epilog()/preload() pair to ensure
+	the validity of the given strings (e.g. filtering out comments
+	and blank lines). For preload itself a call_other(file, "???")
+	s sufficient, but it should be guarded by a catch() to avoid
+	premature blockings. Also it is wise to change the master's
+	euid from root_uid to something less privileged for the time
+	of the preload.
+
+	You can of course do anything else with the passed strings -
+	preloading is just the traditional task.
