 == Per-user file sandbox ==
 
+This mechanism allows job submitters to explicitly
+upload files via a web interface: PROJECT_URL/sandbox.php.
+
+Links to the files are stored in a "sandbox directory"
+PROJECT_ROOT/sandbox/USERID/.
+The entries in this directory have contents
+{{{
+size MD5

+
+The actual files are stored in the download directory,
+under the name '''sb_userid_MD5'''.

+Currently, files in the sandbox are not cleanup up automatically.
+The web interface allows users to delete their files.
