The primary means for distributing SIL Linux software is through a package repository that targets recent releases of Debian and Ubuntu. This will parallel the main distro repository, and provide SIL-only packages or newer versions of SIL packages that are also in the upstream distro repository. This package repository can be accessed at http://packages.sil.org/ If you want both stable and early-release versions of our software, please be sure to add both
deb http://packages.sil.org/ubuntu precise main and
deb http://packages.sil.org/ubuntu precise-experimental main to your repository settings (or the equivalent, for the distro you are using).
Currently we are discussing the design and setup of the SIL Linux repository system in Repository.
For non-repository based systems, such as Mac and OLPC, there is a software download area here.
