I am trying this out, but find the instructions hopelessly inadequate
and confusing.

First, the how-to on the wiki says to "select the <icon> from the
toolbar," but the image on the wiki doesn't match any icons I have in
the toolbar on Scribus 1.3.5NG. However, I do have an icon labeled
"TEX." 

I selected the "TEX" icon and placed a frame, which immediately
displayed "Render Error." Right clicking on the frame and then on Edit
Source got me a popup window with some sample code and a bunch of tabs.
The sample code does not produce a formula (Status: Error). And I
failed to grasp the functions of the things in the tabs, except perhaps
they are to give hints on the code to use to enter those items. 

Then I read what is in the wiki, but failed to get a formula to work.

What I need to create is what is called in OOo a stack. Consider that
the brackets in the following are all one big tall bracket encompassing
all the items in the stack:

[ sometext           ]
[ some more text ]
[ yet more text     ]

Sometimes my stacks have only one item, sometimes as many as seven. I
need the brackets to scale.

If there is someone here familiar with math syntax in Latex, could you
give me the syntax to create the above? Once I have the correct syntax
for one formula I'm sure I can change it for additional formulas.

I also need to figure out how to assign fonts, but one step at a time.
