+<p> For very large output files we strongly discourage the use of afs
+space, as it has performance penalty and it is really intended to be used
+for user and program files and not data files. Users needing access to
+large data files should use the ALICE staging facility. The procedure is
+the following:
+
+<p><ol>
+
+<li> Define a <var>STAGE_HOST</var> variable which is in our case
+<var>shiftalice</var>
+
+<p><li> In your <var>Config.C</var> macro, or in any other place where
+you open a file, instead of opening the file as
+
+<p><kbd>
+ TFile *f = new TFile("filename","option");
+</kbd>
+
+<p>use
+
+<p><kbd>
+ TFile *f = TFile::Open("rfio:filename","option");
+</kbd>
+
+<p><li>Stage a file via the command
+<p><kbd>
+ stagealloc -p alice_stage filename
+</kbd>
+
+<p>This will create in your working directory a link <var>filename</var>
+that points to the <em>real</em> file in the stage pool.
+
+<p><li>Now you can run
+
+<p><li>When done with the file, do not <kbd>rm filename</kbd>. It will
+remove the link only, the file will still be in the pool, occupying our
+precious disk space. To delete a staged file instead do
+<p><kbd>
+ stageclr -P `stageqry -p alice_stage -A filename -P`
+</kbd>
+<p>and this will do a proper job.
+</ol>
