[jira] [Updated] (JENA-1824) documenting loc vs. tdb option in tdbquery

     [ https://issues.apache.org/jira/browse/JENA-1824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Elie Roux updated JENA-1824:
----------------------------
    Description: 
In tdbquery, the arguments loc and tdb are mutually exclusive, which can make the user think they're equivalent.

But they're not: using the tdb argument gives many more indications to tdbquery, including the UnionGraph mechanism (which is otherwise impossible to convey in the command line).

This should be made clear in the command line help message, and perhaps in the command line error message saying "Only one of an assembler file and a location".
