which solrconfig.xml

[Mark Fenbers]

Hi,  I've been fiddling with Solr for two whole days since 
downloading/unzipping it.  I've learned a lot by reading 4 documents and 
the web site.  However, there are a dozen or so instances of 
solrconfig.xml in various $HOME/solr-5.3.0 subdirectories.  The 
documents/tutorials say to edit the solrconfig.xml file for various 
configuration details, but they never say which one of these dozen to 
edit.  Moreover, I cannot determine which version is being used once I 
start solr, so that I would know which instance of this file to 
edit/customize.

Can you help??
Thanks!
Mark
