---------------------------------------------------------------

Here is a patch that incorporates some of your suggestions.
* We don't build/run Solr on Windows. I'd be happy to include changes for {{solr.cmd}} by
someone in a position to test them.
* Yes, I have added a {{-o}} flag as suggested. .
* Yes, with the new design, if no output file is specified via {{-o}}, then the output will
now go to {{stdout}}.
* Yes, the {{jstack}} needs to be run on the same box, as do many of the other commands, including
the stars of this {{bin/solr}} script: {{start}} and {{stop}}. I'm pretty sure that if you
have a suitable {{$\{JAVA_HOME\}/}} for Solr, then {{jstack}} will be there in {{$\{JAVA_HOME\}/bin}},
* Yes, documentation added to Solr Ref Guide.
