I do all development in a single application. when a new version is ready I create a template and give it a version number. this way I can store a history of all previous versions.
the development templates are used to push the new design to many applications via replace design.
Creating manual version number or template names is fine but I am looking for a more automatic way of finding out which build the different applications are inherited from
When I visit the different applications I would like to be able to see which build number each application are inherited from. is this possible?
A simple build time stamp could do, but is there a built in build number that can be used and that can be displayed on the xpage.
e.g Build 2012092712345
Update: Thank you for all your answers, many good suggestions but it looks like all require manual work.
The best solution would be if there is a way to read (from ssjs) a timestamp from any file within the nsf that is always updated during a build. is this possible?
