+is corrupt and either the credits or refunds are missing (see
+L<FS::cust_credit>, L<FS::cust_refund>, and L<FS::cust_credit_refund>).
+If the OPTION_HASH contains the element 'dry_run' then a report of

+=head1 NAME
+
+freeside-prune-applications - Removes stray applications of credit, payment to
+                              bills, refunds, etc.
+
+=head1 SYNOPSIS
+
+  freeside-prune-applications [ -d ] [ -q | -v ]
+
+=head1 DESCRIPTION
+
+Reads your existing database schema and updates it to match the current schema,
+adding any columns or tables necessary.
+
+  [ -d ]: Dry run; display affected records (to STDOUT) only, but do not
+          remove them.
+
+  [ -q ]: Run quietly.  This may become the default at some point.
+
+  [ -v ]: Run verbosely, sending debugging information to STDERR.  This is the
+          current default.
