|
Pharo's goal is to deliver a clean, innovative, free open-source
|
|
Smalltalk-inspired environment. By providing a stable and small core
|
|
system, excellent dev tools, and maintained releases, Pharo is an
|
|
attractive platform to build and deploy mission critical applications.
|
|
|
|
This package provides the executable VM. You should probably not care
|
|
about this package (which represents a packaging detail) and have a
|
|
look at the pharo-vm-core package instead.
|
|
|
|
Please fill bug reports on http://bugs.pharo.org under the 'Ubuntu
|
|
packaging (ppa:pharo/stable)' project.
