Flasher monitors changes to one or more files, and indicates the number of writes to these files by briefly flashing a console LED once for each write. The flashing sequence is repeated, after a brief pause, until the files have been read. As the files are read, the number of LED flashes is reduced. When all monitored files have been read, the console LED is disabled. The most obvious use is to monitor specific system log or mail files. Multiple LEDs can be used.
Release Notes: Previous versions would work only on the console (usually the first virtual terminal). The new release works on a user-specified virtual terminal, which also means it can now work under X.
