+ yr.php  -  YR.no forecast on YOUR page!
+ 
+ This script was downloaded from http://www.yr.no/verdata/1.5542682
+ Please read the tips on that page on how you would/should use this script
+
+ You need a webserver with PHP version 5 or later to run this script.
+ A lot of comments are in Norwegian only. We will be translating to english whenever we have the opportunity.
+ For feedback / bug repports / feature requests, please contact:  Lennart André Rolland <lennart.andre.rolland@nrk.no>
+
+ ###### Changelog
+
+ Versjon: 2.6 - Lennart André Rolland (lennart.andre.rolland@nrk.no) / NRK - 2008.11.11 11:48
+ * Added option to remove banner ($yr_use_banner)
+ * Added option to allow any target for yr.no urls ($yr_link_target)
+
+ Versjon: 2.5 - Lennart André Rolland (lennart.andre.rolland@nrk.no) / NRK - 2008.09.25 09:24
+ * Cache will now update on parameter changes (cache file is prefixed with md5 digest of all relevant parameters)
+   This change will in the future make it easier to use the script for multiple locations in one go.   
+ * Most relevant comments translated to english
+
+ Versjon 2.4 - Sven-Ove Bjerkan (sven-ove@smart-media.no) / Smart-Media AS - 2008.10.22 12:14
+ * Endret funksjonalitet ifbm med visning av PHP-feil (fjernet blant annet alle "@", dette styres av error_reporting())
+ * Ved feilmelding så ble denne lagret i lokal cache slik at man fikk opp feilmld hver gang inntil "$yr_maxage" inntreffer og den forsøker å laste på nytt - den cacher nå ikke hvis det oppstår en feil
+ * $yr_use_text, $yr_use_links og $yr_use_table ble overstyrt til "true" uavhengig av brukerens innstilling - rettet!
+
+ Versjon: 2.3 - Lennart André Rolland (lennart.andre.rolland@nrk.no) / NRK - 2008.09.25 09:24
+ * File permissions updated
+ * Caching is stored in HTML isntead of XML for security
+ * Other security and efficiency improvements
+
+
+
+ ###### INSTRUCTIONS:
+
+ 1. Only edit this script in editors with ISO-8859-1 or ISO-8859-15 character set.
+ 2. Edit the settings below
+ 3. Transfer the script to a folder in your webroot.
+ 4. Make sure that the webserver has write access to the folder where thsi script is placed. It will create a folder called yr-cache and place cached HTML data in that directory.
