Like nearly every software project, jEdit is built from its source code using what is called a "make" or "makefile" system. These terms come from the original "make" utility that was created for use on the UNIX operating system; there are now a variety of makefile utilities available for all operating systems. Besides the source code and related resources, a makefile system has two main elements. The first is a "makefile", a plain text file that specifies the steps necessary to build the application, such as the invocation of a compiler, an object code linker or an archiving program. The makefile also describes the dependencies among the final product, intermediate files and the underlying source code. This file will be written in a special format designed to satisfy the requirements of the second major element, the "make" utility.
