[python] zope ano/ne

[Petr Vanek]

ahoj,

nevim na kolik to sledujete, ale na rootu se objevila debata na tema
zope ano/ne. kazdy produkt ma sve priznivce a sve odpurce, ale protoze
jsme tady spise ve skupine priznivcu, mohl by nekdo vzit tu kritiku bod
po bodu a okomentovat, popripade vyvratit/potvrdit pravdivost, nejlepe
na zaklade vlasti zkusenosti. nerikam, ze to musi byt na rootu, klidne
to muze probehnout touto konferou, nebo to muzem hodit na py.cz jako
clanecek a pak to tam nalinkovat...

http://www.root.cz/clanek.phtml?id=1215

p.s. vim, ze takovych debat je tady kolem plno, pokud si myslite, ze to
zato nestoji, tak to nechte plavat...

p.p.s prikladam svuj prvni pythonovsky script ;-), muze se  hodit ;-)
