Too many people here in our university don't have the sense of measure in these things, and they start mixing the process of programming with the process of getting money for nothing:). But maintainability is really important. So, for me, the 4) point wins, with 3) as its closest rival. --=20 DoubleF "He's the kind of man for the times that need the kind of man he is ..." --4bRzO86E/ozDv8r1 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAiIUIwo7hT/9lVdwRAkHjAJ4yKOwYNvApJS9EJnyoJfjT74STTACfRkqU cKpeB5xkFhh0GTrqzB9y3R8= =wNbu -----END PGP SIGNATURE----- --4bRzO86E/ozDv8r1--
