[wpkg-users] WPKG-GP file modification date comparison fail

[Oliver Sauder]

I actually answered this question on the WPKG-GP mailing list as this
question has been posted there as well.

Here an extract of the answer:
> Wpkg-GP.ini has the modification date of the present because Wpkg-GP
> when loading the ini file will always rewrite it to make sure that
> certain settings are set correctly (e.g. it encrypts the password).
