**
** 2006-10-31: The default prefix used to be "sqlite_". But then
** Mcafee started using SQLite in their anti-virus product and it
** started putting files with the "sqlite" name in the c:/temp folder.
** This annoyed many windows users. Those users would then do a

** For this reason, the default name prefix is changed to be "sqlite"

** enough to know that calling the developer will not help get rid
