vectorForm of xi~dot~grad[div[u]] where u and xi are vectors

Thanks to the author, VEST looks to be a really good package for vector analysis. I am new to Mathematica and vector analysis, and I have a question about the vectorForm function in VEST.
The example problem has the form shown in the figure below. The $\vec{\xi} \cdot \nabla (\nabla \cdot \vec{u})$ seemingly cannot show in the correct vector form, and thus if this expression is a part of a long expression I may not be able to use the powerful FullSimplifyVectorForm function.

Choice of variable naming

Quoting from StackExchange:

It is for these very reasons that the Mathematica naming recommendations are what they are. Exported names are expected to be long and descriptive to maximize the chance of global uniqueness. Global variables are expected to start with a dollar sign. It is considered bad practice to export short names that start with lower case letters (especially ones like x and y) because the chance of collision is near certainty. Short, common, names are expected to remain private to a package.

x and v are so commonly used in mathematics, that it's rather annoying to redefine these in a package. I am presently trying to go through my own copy of the file trying to change them to something else. This seems like it would be good practice in general.

VEST.m doesn't load

I tried loading VEST.m into Mathematica 9.0.1.0. It gave an error:

Syntax::sntx: Invalid syntax in or before "Loading packages, version checking and welcome message"
     (line 280 of "VEST`").

It seems that VEST.m has a few lines of uncommented text smattered throughout that mathematica is trying to parse as code.
