Bella :^)

ho trovato i file su cui stavo lavorando fino a giugno 2005. Alcuni
sono vecchi, insomma sono da considerare
come spunti. Ricordo che funzionavano. Man mano che trovo
materiale, continuo a postarlo.
Visto che parliamo di 56Kb di testo in totale, mi limito a postare
singoli file in 4 diverse mail.
Mi scuso in anticipo con chi ha una linea a 56K e avra' rallentamenti,
ma spero che questa frammentazione non blocchi nessuno. Inoltre
trovo molto utile che negli archivi della lista ci sia traccia di queste
informazioni.

I files sono cosi' composti:
- buildSDK.5 = Man page del rispettivo comando
- buildSDK = Il comando, nella versione PPC
- buildSDK-100205 & buildSDK-180205 = versioni differenti
    (poco differenti) del comando, nel flavour x86.

Saludos (spero di essere nei 72 chars ;^)
