Execution plan

If fully configured the deployment script executes the following steps in that fixed sequence:

• loop over profiles ... and per profile ...
• set profile data by sourcing [profile]/config.sh
• download Software archive
• detect if download is newer than the last one
• jump into installation dir of your application
• optional: execute pre installation tasks (1)
• optional: run cleanup (1)
• extract software archive (1)
• create config files
• optional: execute post installation tasks (1)
• optional: execute post config change tasks (1) or (2)

(1) if a new software version was downloaded (2) if one of the config files was created or changed
