Finding the language packs installed on a SharePoint Server

I spent a hour or sow looking for a way to find all the installed languages on a server so I could update one of the XML files via a feature (I will post later about Installing a Theme across multiple front end servers targeting multiple languages).

The file I want to modify was SPTHEMES that is located at TEMPLATE\LAYOUTS\{LCID}\SPTHEMES.XML, There is a unique file for each language.
I thought that there must be a class in the OM that would allow me to get the installed languages. After diving in to the SPFarm object, digging in the NewSitePage class and a number of web searches while still getting no where I stumbled on the most simple class. (YaY for Reflector)

SPRegionalSettings and its GlobalInstalledLanguages property.

SPRegionalSettings.GlobalInstalledLanguages is a collection of SPLanguage objects.
each SPLanguage object is a simple data object that contains DisplayName and a LCID propriety.

so with this simple for loop I managed to avoid messing around with searching through the File system.

foreach (SPLanguage language in SPRegionalSettings.GlobalInstalledLanguages)
{
DoSomthingWith(language);
}

Sometimes the simple solution takes the longest to find.
Hope this helps someone.
