Hi
You are right. It is not required. Anyhow it is very likely that a user wants to create the index if the bounds option is set.
Yes, although not necessarily in the same run. I usually create the tiles first and then the index. But then I am probably not a typical user. Even if you are not creating an index, the --bounds option is still useful and results in a better map. The warning should almost be the other way around, creating an index without using a bounds file leads to a poor index.
At least a warning should be reasonable. But we don't have a good place for warnings. The log system is rarely used and it must be configured to show warnings. Stderr should printout errors only?!
Agree, we shouldn't use the logging for warnings. Although in fact currently there is a mixture of log.error() and System.{err,out} in use for errors and warnings. I'd prefer to use System.err for user messages with the message prefixed with "Warning" if appropriate - one day someone may be motivated to create system to print messages with internationalisation. ..Steve
