A Script is used in contests to help the functionaries perform their roles. Analogous to the script for a movie or television show, the script lays out what a functionary will say and what actions will occur. The script is usually not as detailed as a movie script, and in fact may be simply an outline in some cases. A contest organizer typically will not have to write a script but will simply use the one from a previous event, updated to include the names of current functionaries.
A Script may also be used in non-contest contexts. See, for example, Installation of Club Officers, for which a script is available.
