Kile is an amazing piece of programming work. Its feature-rich user interface will boost everyone's typesetting productivity by providing quick access to all Tex and LaTeX programs. Kile can help anyone improve his or her productivity with LaTeX typesetting, but it is no substitute for a good written tutorial. Among the electronically available free titles, Tobias Oetiker's book, The Not So Short Introduction Guide to LaTeX2e is a good companion to Kile.
The road to the beautifully typeset publications is paved with many hours and days of learning the subtleties of TeX and LaTeX. compilers. Discovering numerous secrets of the language, plus learning about Postscript and Metapost along the way, is nowadays much faster with Kile and, some may find, more entertaining. Through extensive exploitation and the good work of the programmers, this program has reached an exceptional level of maturity and stability. The integration with the teTeX collection of compilers and utilities is so well done that the laborious ways of working separately with each one of them is now history.
The original author Pascal Brachet and the members of the Kile development team can be proud of their work given the number of users who benefit from it.
