Installer is a mechanism for listing, examining and installing software from a variety of sources. It is intended to help in building install scripts for package setups etc. Currently it can use - files; a file specified by a filename. Relative filenames will be treated as based form the current default directory. See InstallerFile. - urls; a file specified by a url or a script embedded in a webpage. See InstallerWeb. - squeakmap; see InstallerSqueakMap - monticello; by ftp or http access, or a local directory, or a Magma or GOODS database. There is a list of shortcuts to popular repositories in this class protocol 'repositories'. See InstallerMonticello. - mantis; accessing code attached to a mantis bug report. See InstallerMantis. Simple example usages - + Installer new merge: #osProcess. Installer squeakmap install: 'DynamicBindings'. Installer squeakmap search: '*scratch'. Installer squeakmap search: 'author:*rowledge'. Installer squeaksource project: 'ss2'; install: 'TinyWiki'. Installer ss project: 'Installer'; browse: 'Installer-Core'. useFileIn - flag to load source.st rather than using Monticello!

I guess I will have to learn the github stuff too, but if it helps documentation and in-image CustomHelp, then we are on the right track. cheers.

Hi Folks, I documented the ssl fix in a Howtow at https://github.com/gettimothy/Org-SqueakHOWTO/blob/master/SqueakHOWTO.md It is also pushed to squeaksource.com/Doc as SqueakHOWTOHelp. I have a stub entry for the rtio stuff if anybody wants to contribute. cheers, tty p..s....I will have to add that How To Build the VM that Marcel contributed next

Still getting the error via Monticello. I can log into squeaksource just fine with my browser. I have a pharo image and I was able to open the repo with it. Is there something in squeak I need to clear? cheers t
