+Import payments from a CSV file from a bank.  The payments will automatically be
+parsed, and there'll be an attempt to automatically match payments with members.
+
+The matching is performed using the label of the payment.
+- First, try to find a string such as 'ID-42' where 42 is the member's ID
+- Second (if no ID found), try to find a member username (with no ambiguity with
+  respect to other usernames)
+- Third (if no username found), try to find a member family name (with no
+  ambiguity with respect to other family name)
+
+This script will check if a payment has already been registered with same
+properies (date, label, price) to avoid creating duplicate payments inside coin.
+
+By default, only a dry-run is perfomed to let you see what will happen ! You
+should run this command with --commit if you agree with the dry-run.
