+Detailed table of contents:
+
+ morse.c
+	An extended version of classic /usr/games/morse that supports
+	audio output (-a) through sndio and integrates an interactive
+	teacher mode (-t) modeled after Cunningham's 1977 algorithm.
+ morseteach.c
+	Stand-alone teacher program that forks and uses 'morse -a' in the
+	background for its audio output.
+ morseplay.c
+	Stand-alone audio component to play morse code. Accepts dots and
+	dashes as 'morse -s' produces them.
+
+ teach.c
+	Implements the teacher algorithm. Used by morse and morseteach.
+ cw.c
+	Audio output routines for "continuous wave" tones of a given
+	frequency and length. Applies envelope functions for clean sound
+	without unwanted clicks. Used by morse and morseplay.
+
+ NOTES
+	Background research, plans, and history for the teacher algorithm,
+	other implementations, and the UNIX/BSD morse program.
