Shell Type?

What is the difference between the different “Shell Type[s]” ?

Under the Web Panel -> Users -> Manage Users -> Add New User…

I searched the wiki for “Shell Type” but couldn’t find any info.

Here’s a wikipedia article comparing shells. There are probably better comparisons around, but you can get a halfway decent description of the different shells in wikipedia.
