Metacat

some quick additions and fixes to the python metacat readme

Initial import of prototype python client library to interact with metacat

Changes to map layout and skins according to input from Callie and Matt

Removed tomcat 3 support

Merged the spatial web.xml.combined into the default web.xml.tomcat5

minor changes to khtml detection stategy

safari/opera detection for interactive map. Users of non xslt-compliant browsers will be redirected to an error page.

Changing initial configured status back to false

Set configured to false initially. Include notification in configure process that geoserver password needs to be changed plus instructions on how to do so

Updated MetaCatServlet so that it supports a web-based interface for configuring its own properties the first time it is run (determined by the property "configured" being set to false). Which properties are exposed in the web interface is determined by the list of properties in the 'metacat.properties.metadata' file. This file is managed by the new OptionsMetadata class in the utilities module, and provides information that allows metacat to build a human-readable configuration page for the properties. Still need to finish filling out the information in metacat.properties.metadata for the rest of the properties that we want to be editable. This autoconfiguration process is the first step towards building a turnkey installer for metacat....
