ok - so "unbound variable" is gone as a problem, but:
```text
:~/git/apache/incubator-tinkerpop$ bin/gremlin.sh -v
log4j:WARN No appenders could be found for logger

gremlin 3.2.3-SNAPSHOT
~/git/apache/incubator-tinkerpop/gremlin-console$ bin/gremlin.sh -v
gremlin 3.2.3-SNAPSHOT
:~/git/apache/incubator-tinkerpop/gremlin-console/target/apache-tinkerpop-gremlin-console-3.2.3-SNAPSHOT-standalone$
bin/gremlin.sh -v
gremlin 3.2.3-SNAPSHOT
```
so just the gremlin.sh in root is "bad". imo, we should just drop that
file anyway. we don't have a gremlin-server.sh in there nor do we have a
associated `.bat`. not sure what that file is good for.
