## Project history and usage

morse, packaged from the morse-classic project, is a command-line Morse-code trainer and QSO generator associated with Eric S. Raymond's CATB software pages. The resource page describes it as a training program for aspiring radio amateurs that can generate random tests or simulated QSOs resembling ARRL test material, with options for varying the training method.

### How it is used

The tool's practical use is deliberately old-school Unix: one mode reads text from standard input and renders it as Morse-code beeps, while the QSO generator creates practice copy material. Its package-manager niche is a compact ham-radio and Morse training utility, distributed in Homebrew alongside Debian and Ubuntu packages under the plain morse name.
