[antlr-interest] Best Practices for Migrating Antlr 2.7.7 to 3.4

[Paul De La Musica]

Hi,

We are trying to migrate a script.g file fron V2.7.7 to V3.4.

A quick trial on the v2v3 conversion utility doesn't seem to work (see
error below).

Is the best way just to go through the 2.7.7 *.g file line by line?

Thanks,

Paul
