Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems.
Vim is often called a "programmer's editor", and so useful for programming that many consider it an entire IDE. It's not just for programmers, though. Vim is perfect for all kinds of text editing, from composing email to editing configuration files.
For each article you buy, we donate part of our benefit to Vim. In turn, Vim transfers these donations to the ICCF, an NGO that helps the children in Uganda. This way we all win :)
