code snippet for reading LDIF commands

[Ken L. <cc...@us...>]

Could anyone show me a code snippet how to retrieve information reading
a LDIF command file using Net::LDAP::LDIF->read_cmd?  For changetype
"add" and "delete", it is simple.  However, it seems complicated for
changetype "modify".  How can I know which attributes are
added/deleted/replaced in the "modify" command?

Any help is really appreciated.  Thanks!
