<h1>Configuration from the command line</h1>
<p>The main command-line interfaces to Saxon are <a class="bodylink" href="../../javadoc/net/sf/saxon/Transform.html"><code>net.sf.saxon.Transform</code></a> for
<a class="bodylink" href="../../using-xsl/commandline.xml">running a transformation</a>,
<a class="bodylink" href="../../javadoc/net/sf/saxon/Query.html"><code>net.sf.saxon.Query</code></a> for <a class="bodylink" href="../../using-xquery/commandline.xml">running XQuery</a>,
and <a class="bodylink" href="../../javadoc/com/saxonica/Validate.html"><code>com.saxonica.Validate</code></a> for
<a class="bodylink" href="../../schema-processing/commandline.xml">validating a document against a schema</a>. These
commands allow many configuration options to be specified by command line options: for example if XML Schema 1.1
support is wanted, all three commands allow this to be requested using the option <code>-xsdversion:1.1</code>.
Many of these options correspond directly to the configuration properties available on the <code>Configuration</code>
object.</p>
<p>For more specialized options, there is also a fallback mechanism. Each configuration property has a URI, which
is always of the form <code>http://saxon.sf.net/feature/SOME_NAME</code>. Provided the property allows
a string value (as most do), the property can be set from the command line using the syntax <code>--SOME_NAME:value</code>.
For example the property identified by <a class="bodylink"
href="../../javadoc/net/sf/saxon/lib/FeatureKeys.html#LICENSE_FILE_LOCATION"><code>FeatureKeys.LICENSE_FILE_LOCATION</code></a>
has the URI
<code>http://saxon.sf.net/feature/licenseFileLocation</code>, and it can therefore be set on the command line
using an option such as <code>--licenseFileLocation:c:/saxon/license.lic</code>.
</p>
<div class="boxed"
style="border: solid thin; background-color: #B1CCC7; padding: 2px">For boolean-valued configuration properties, Saxon accepts any of the values "yes", "on", "true", or "1" to switch
the option on, or "no", "off", "false", or "0" to switch it off.</div>
