[antlr-interest] Fedora antlr3-tool command line antlr returns version 2.7.7

[The Researcher]

I am test building ANTLR on Fedora 15 and installed package antlr3-tool
using the GUI.

Using the command line I entered antlr only to see version 2.7.7 not 3.x.

While I know that 2.x versions are needed for 3.x versions to build, if I
were to run from the command line shouldn't the antlr command be a 3.x
version?

So the real question is, can the antlr3-tool package be trusted for use from
the command line?

Thanks, Eric
