vBulletin's Official Placeholder Syntax?

[DivisionByZero]

I'm working on a new class that builds and ionCube-encodes a PHP project on the fly. This is not much different than how vBulletin delivers its software except that I want to ionCube encode the project.

I'm somewhat undecided on how I want to define placeholder variables in source files. So, I'm asking for official input from the vB developers on their conventions regarding placeholders.

I do not want to use the {{variable_1}} style because some of the projects built by the class will include smarty templates.

Thanks in advance for your input

I dont think the released product uses them, I cannot think of an example.

Internally, some files have placehoders that are updated by the downloader code, they tend to be of the format [#]placeholder_name[#].
