Subject: Parser is settable with the -parser argument; if not set or set to
X-Git-Tag: release/1.79.1~6^2~4739
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f3faca16705997a29ed601e57f5b930dc1ba5e0d;p=docbook-dsssl

Parser is settable with the -parser argument; if not set or set to
'auto', fall thru to xerces2, xerces1, crimson, or native parser, in
that order.

Use fixclasspath function.

Better verbose handling; verbose is off by default.
