[Pharo-project] FTP repo without storing username/pass in ConfigurationOf

Hi all, I have the code of an app in a FTP repo which has username/password. I am doing a ConfigurationOfMyApp now and I would need to define in the baseline something like spec repository: 'ftp.mydomainapp.com ...etc'. I know I have a similar method for also specifying the username/pass. But I don't want that because it means storing the username/pass in the ConfigurationOf code. So....how can I manage this with metacello? the only thing I found (which I am not sure if it works) is to use repositoryOverride so when I am about to load my project I do a #repositoryOverride: passing as argument a FTP with my username/password. What do you think? best, -- Mariano http://marianopeck.wordpress.com
