	ImageSource string
	tel.Data    // embedding is required by the generator.
	// FlagNames contains the command-line flag names.
	FlagNames []string
	// FlagValues contains the values of the command-line flags, where each value corresponds to the flag from FlagNames
	// at the same index.
	// Each value is either 'true' or 'false' for boolean flags and 'default' or 'user-defined' for non-boolean flags.
	FlagValues []string
	// SnippetsFiltersDirectives contains the directive-context strings of all applied SnippetsFilters.
	// Both lists are ordered first by count, then by lexicographical order of the context string,
	// then lastly by directive string.
	SnippetsFiltersDirectives []string
	// SnippetsFiltersDirectivesCount contains the count of the directive-context strings, where each count
	// corresponds to the string from SnippetsFiltersDirectives at the same index.
