Generate CREATE DATABASE FOR ATTACH for all existing user databases

Does anyone have a TSQL script that can automatically generate the code necessary to attach ALL existing user databases using the CREATE DATABASE FOR ATTACH syntax? example: CREATE DATABASE [mydatabase] ON (FILENAME=N'E:\MSSQL\Data\mydatabase.mdf'), (FILENAME=N'D:\MSSQL.1\MSSQL\Data\mydatabase_log.ldf'), (FILENAME=N'E:\MSSQL\Data\mydatabase_ndf.ndf') FOR ATTACH I have found many examples using sp_attach_db, but none with the CREATE DATABASE FOR ATTACH syntax. Thanks, Craig
