Replacement Variables/Templates

[Radon3k]

How does one go about creating a replacement variable? I've seen a few scripts that use template systems where the template itself is stored in the database yet they use replacement variables (such as {$variable}). How are these created? Thanks. :)

Through the front-end, or through code?

Through the front-end, there is a link at the end of the style options (in the case of vB3) for the specified style set. Replacements are simply strings that will be replaced once the final template is compiled (including variables).
