+# Signal generator definition
+#
+# The basic block is a "tone". A tone is defined by frequency, attenuation, and duration.
+# A tone is enclosed in parens "(freq att dur)".
+#
+# A frequency is given in Hz or kHz. Giving a frequency implies 0dB, giving no frequency implies -100dB.
+# The attenuation is given in dB, which is dBFS: 0dB is maximum level, -100dB is always assumed silence.
+# The duration is given in units of seconds (s), milliseconds (ms), or microseconds (us).
+#
+# A symbol is a named sequence of tones. A symbol is defined in brackets "[symb tones and symbols...]".
+#
+# If you define the 0 and 1 symbol you can also use hex in braces "{...}" for output.
+#
+# Whitespace is ignored, except to separate arguments. Whitespace is space, tab, newline, and linefeed
+# Comments begin with a hash sign "#", can start anywhere and run to end of the line.
+# All symbols are one char, 7-bit ASCII. You can not use parens, brackets, braces, dot, or minus as symbols "()[]{}.-".
