The "import" package due to mantis version

[mooy]

I would like to ask if I can embed the
"mantis_import_issues_v7.zip" package (15,059 bytes - 2007-03-26 12:51) AND the
"import_issues.php" (22,471 bytes - 2007-05-21 10:15)
into the Mantis 1.1.0a2 .
(In addition, what about versions 1.1.0rc3 and 1.1.1 ?)

Thank you very much in advance.
