Introduction

TwoFlower is an Internet Browser designed to be used with VisualWorks Smalltalk programs; in this case as a plugin to the BottomFeeder Internet Console.

This User's Guide is written for general users of the Internet. It will help you learn how to use TwoFlower. It is also a reference manual for all of TwoFlower's features.

But first, why would you want to use the TwoFlower plugin? Doesn't your computer already have an Internet Browser, such as Windows Internet Explorer or Netscape? And doesn't BottomFeeder already launch these browsers on the feed items you select?

The technical answer is that TwoFlower, running on the same VisualWorks virtual machine as BottomFeeder, requires very little memory or other system resources. The practical answer is that this enables it to keep many web pages open, each under its own tab. It is just like having multiple Internet Browser windows open; you can switch from one to the other just by clicking a tab.

To start TwoFlower, select Plugins / TwoFlower in the BottomFeeder main menu.
