+# to the global tcl list variable ::echo_module whenever SQLite invokes
+# certain module callbacks. This includes the xSync(), xCommit() and 
+# xRollback() callbacks. For each of these callback, two elements are
+# appended to ::echo_module, as follows:
+#
+#     Module method        Elements appended to ::echo_module
+#     -------------------------------------------------------
+#     xSync()              xSync echo($tablename)
+#     xCommit()            xCommit echo($tablename)
+#     xRollback()          xRollback echo($tablename)
+#     -------------------------------------------------------
+#
+# In each case, $tablename is replaced by the name of the real table (not
+# the echo table). By setting up a tcl trace on the ::echo_module variable,
