/*

This script is used to shrink a database file in

increments until it reaches a target free space limit.

Run this script in the database with the file to be shrunk.

1. Set @DBFileName to the name of database file to shrink.

2. Set @TargetFreeMB to the desired file free space in MB after shrink.

3. Set @ShrinkIncrementMB to the increment to shrink file by in MB

4. Run the script
