When clients ask for extra facilities on their websites, suitable software needs to be written. Usually the authoring draws on work and experience which people have kindly published on freeware websites or added to forums, blogs etc.. It seems only right, in return, to make the finished code available under the "free to download and use" GNU license. The work is still copyright, so people cannot simply copy it and sell it as their own.
Items are being revised and re-published so look out for additions to the list below.
Yowsie's Easy Translation Interface
The Yeti package allows web developers to offer content in any language without having multiple copies of their scripts to code and maintain. You will need help from people who can translate (like your client's overseas agents), but you need no linguistic skills at all and they need no understanding of HTML, php etc.. You need to have your website on a server that runs php and can use utf-8 encoding.
Yowsie's On-Site Statistics
Yoss offers simple on-site recording of the countries where visitors live, whether they came to the site via a search engine and how many times each page was viewed. It is not designed to substitute deep analysis of the server logs or to match Google Analytics etc. but to provide a fast and easy glimpse into how the site is performing.
