/*
        This routine is platform-independent.

        MMEX is a portable application which means ability to to run
        without installation, for example, from USB flash drive.

        If mmex finds mmexini.db3 in its folder, it assumes portable
        mode and GetUserDir() in such case points to that folder.

        FIXME: security issue - temp files will be created on host filesystem.
