Initial checkin of virgin files from wayback-1.7.1-SNAPSHOT.war
Changes to 'plain vanilla', 'out of the box' Wayback web application for it to
integrate with the Australian Government Web Archive (AGWA) web application.

These include changes to XML config files in WEB-INF/, the salient points of which
are documented below.

WEB-INF/CDXCollection.xml
-------------------------

Location of index file mapping resource file (WARC file) names to the paths where they live.

    <bean class="org.archive.wayback.resourcestore.LocationDBResourceStore">
      <property name="db">
        <bean class="org.archive.wayback.resourcestore.locationdb.FlatFileResourceFileLocationDB">
          <property name="path" value="/data/gov2011-12/path-index.txt" />
        </bean>
      </property>
    </bean>

Location of 'master' CDX index files (2.1GB and 6.1GB respectively) for 2011/12 harvests. These
files map harvested URLs to the filenames of the WARC files they are stored within:

    <bean class="org.archive.wayback.resourceindex.CompositeSearchResultSource">
        <property name="CDXSources">
            <list>
                <value>/derivative/data/nla.arc/gov.au/001/sorted.cdx</value>
                <value>/derivative/data/nla.arc/gov.au/002/nla2012-gov.cdx</value>
            </list>
        </property>
    </bean>

WEB_INF/wayback.xml
-------------------

To specify the base URL to which HTTP requests to Wayback must be sent:

    <property name="properties">
      <value>
        wayback.basedir=/tmp/wayback
        wayback.urlprefix=http://htx-mpearson:8080/wb/wayback/
      </value>
    </property>

Location of index file mapping resource file (WARC file) names to the paths where they live (I'm not quite sure why
this is specified here as well as in BDBCollection.xml):

    <bean id="resourcefilelocationdb" class="org.archive.wayback.resourcestore.locationdb.FlatFileResourceFileLocationDB">
      <property name="path" value="/data/gov2011-12/path-index.txt" />
    </bean>

Configure Wayback to use a collection pre-indexed with CDX files:

    <import resource="CDXCollection.xml"/>
