If you're in IRC, you can easily .wik Scite and find out quickly what it is. As a matter of fact, it looks like "SciTE or SCIntilla based Text Editor is a cross-platform text editor written by Neil Hodgson using the Scintilla editing component." - http://en.wikipedia.org/wiki/Scite.
Wow. What a gross understatement. Scite is somewhere between a text editor, as our fine IRC bot let us know, and a full-fledged IDE. Scite is really a programming tool that helps someone to be able to identify programming errors due to syntax issues. This program can complete commands, but it doesn't do it perfectly, nor does it do it like the Java NetBeans IDE. If you're looking for a full-fledged IDE, look elsewhere.
BUT WAIT! There's more! You, given enough time and boredom, can write the interface for your favorite non-included programming language. You can edit the way the language is interfaced for your language (turning word completion on or off, for example). You can change the formatting colors, you can change the function formatting and so forth.
If you are a programmer, or pretend to be a programmer like me, check out Scite. I think you'll enjoy it!
