# Command line changes

There has been a significant reorganization of the command line parameters for the commands used to control XSLT and XQuery, though all commonly-used options should continue to work unchanged. Options now generally take the form `-keyword:value`, with the values "on" and "off" for boolean options. Groups of related options have been combined, so `-ds` and `-dt` are now `-tree:linked` and `-tree:tiny`. For options that were previously in the form "-keyword value", the old form (with a space) is still accepted for the time being. Details of the commands are at Running XSLT from the Command Line and Running XQuery from the Command Line.

The option `-x:classname` has been added for XQuery to set the parser class name used for source files, this is to allow use of a catalog resolver.
