Описание тега metacello
Metacello is the standard dependency management package for cross-platform Smalltalk development.
Metacello provides the same functionality as gem/bundle for Ruby, or maven for Java: it lets you specify the internal structure of your application in terms of Monticello packages, and lets you specify your external dependencies.
This allows for "one click" installations, where you can recursively load a package and all its (transitive) dependencies into a running Smalltalk image.
