 Need a new Math Group? ~
 
 If you want to include a new math group in your LaTeX, the following
 code shows you an example as to how you might do so: >
+	call TexNewMathZone(sfx,mathzone,starform)
+You'll want to provide the new math group with a unique suffix
+(currently, A-L and V-Z are taken by <syntax/tex.vim> itself).
+As an example, consider how eqnarray is set up by <syntax/tex.vim>: >
+	call TexNewMathZone("D","eqnarray",1)
+You'll need to change "mathzone" to the name of your new math group,
+and then to the call to it in .vim/after/syntax/tex.vim.
+The "starform" variable, if true, implies that your new math group
+has a starred form (ie. eqnarray*).
