## saxon [--b|--sa]? [--catalogs=...]* [--catalog-verbose[=...]]*
##     [--add-cp=...]* [--cp=...]* <original Saxon args>
##
## Order of arguments is not significant, but the arguments to be
## forwarded to Saxon must be at the end.  See below for an
## explanation of the arguments.
##
## Depends on the following environment variables:
##
##   - APACHE_XML_RESOLVER_JAR (if catalogs are used)
##   - SAXON_SCRIPT_DIR (must contain saxon8.jar or saxon8sa.jar, and
##     the licence file and saxon8-sql.jar if used)
##   - SAXON_SCRIPT_HOME (if different from $HOME, for tilde "~"
##     substitution)
