The most recent version of Argo is 0.6, and you can download it via the following two links:
If you'd like to be informed of new releases please consider subscribing to argo freshmeat project - if you did this it would be appreciated if you would also rate the project.
Binary packages are also available from my personal apt-get repository
After updating your apt-get lists, via "apt-get update" you can install the components by running:
# server components: apt-get install argo-server # clients: apt-get install argo-client-php argo-client-perl argo-client-dialog
Development upon argo has ceased pending a redesign.
