When the atchange program is running, it watches one or more files. When any of those files changes, the program will wake up and do any actions you want. Tasks such as modifying and compiling a program, modifying a data file and using it, or editing atext and typresetting it can be automated with a single typed command such as: atchange myprogram "compile program" By setting up 'atchange' once before starting a repetitive task, one can avoid hundreds of mouse movements.
