Movable Type's template variables, accessed via the GetVar and SetVar template tags, exist only in a global scope. For templates of a certain complexity, this might pose the risk of one template overwriting the variables used by another template inadvertently.
The LocalBlock plugin provides a template tag that allows template authors to establish a scope for a block of template code. Within that scope variables are localized and thus two variables existing in different scopes can share the same name without fear of conflicting with one another.
