# 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
