Let's start with the charity. ICCF Holland is a small charity (its income was £54,790 in 2011) helping about 900 children in Kibaale, Uganda. Many of the children in its care have lost their parents as a result of the AIDS epidemic. ICCF offers the children the opportunity to go to school, and gives them the medical help they need. AIDS prevention and water sanitation are also an important part of ICCF's work.

One of the founders of the charity is Bram Moolenaar, who's better known as the creator of the Vim text editor. If you're not a computer geek you probably won't associate the name Vim with computor software but for many programmers, web developers and system administrators it's the text editor of choice.

Vim was originally designed as an alternative for the Vi editor. 'Vim' originally stood for 'Vi iMitation' but already in 1992 Vim was a lot more advanced than the programme Moolenaar set out to imitate. Since, 'Vim' is an acronym for 'Vi iMproved'.

Twenty years on the Vim project is still going strong; it's installed by default on the just about every Linux operating system, as well as Mac OS X. And, Vim keeps ICCF going as well. Vim is not only free (as in free beer) and 'open source' software, but also 'charity ware'; Vim users are encouraged to make a donation, which goes directly to ICCF. As a bonus, people who make a donation can vote for improvements to Vim.
