Some time back I remember discussion of a tool (I think it pre-dates
engines) that let you quickly/easily deploy multiple instances of a
single Rails app onto a single server. If, for example, you had
multiple customers that wanted to run the same application, but with
e.g. different logos and possibly slightly different rulesets, this
tool could make a “clone” of an application and let you override the
core views/controllers/models if and where you needed to do so.
I’ve completely forgotten the name of this tool, and searching a few
possible keywords in Google hasn’t been enlightening.
Could someone please tell me what this tool is called, as I’ve got a
possible use for it?
Thanks in advance
