Business Requirements for "ee" Editor We believe there is a sufficient market for a programmer's editor that is completely customizable due to its being distributed with its source code. The source code would need to be very maintainable. This would be accomplished by simplicity, being well documented, having a plain and common style, and having other usual characteristics of maintainability. Here we would estimate the number of programmer's editors sold annually, and give typical prices. Then we would estimate the number that would be sold if they included source code, at various prices. A comparison of the expected sales against the cost of development, marketing, and distribution, would indicate whether the project is profitable.
