+"""Dump the contents of any Mailman `database' file.
+
+Usage: %(PROGRAM)s [options] filename
+
+Options:
+
+    --marshal/-m
+        Assume the file contains a Python marshal, overridding any automatic
+        guessing.
+
+    --pickle/-p
+        Assume the file contains a Python pickle, overridding any automatic
+        guessing.
+
+    --noprint/-n
+        Don't attempt to pretty print the object.  This is useful if there's
+        some problem with the object and you just want to get an unpickled
+        representation.  Useful with `python -i bin/dumpdb <file>'.  In that
+        case, the root of the tree will be left in a global called "msg".
+
+    --help/-h
+        Print this help message and exit
+
+If the filename ends with `.db', then it is assumed that the file contains a
+Python marshal.  If the file ends with `.pck' then it is assumed to contain a
+Python pickle.  In either case, if you want to override the default assumption
+-- or if the file ends in neither suffix -- use the -p or -m flags.
