+=head1 NAME
+
+merge-users.pl - Merge two user accounts.
+
+=head1 SYNOPSIS
+
+ This script moves activity from one user account to another.
+ Specify the two accounts on the command line, e.g.:
+
+ ./merge-users.pl old_account@foo.com new_account@bar.com
+ or:
+ ./merge-users.pl id:old_userid id:new_userid
+ or:
+ ./merge-users.pl id:old_userid new_account@bar.com
+
+ Notes: - the new account must already exist.
+ - the id:old_userid syntax permits you to migrate
+ activity from a deleted account to an existing one.
