Mozilla held a localization sprint in Phnom Penh from October 22-23, 2011 to translate software into other languages. Developers use tools like Mercurial and Narro to manage code and localization translations. Narro is a web-based tool used for translation, review, and testing of localized content. The sprint aimed to help grow the Khmer localization team and improve the translation process for software into Khmer.
