+# muxsa-rl
+#
+# part of muxsa, https://git-nks-public.tik.uni-stuttgart.de/edu/muxsa
+#
+# Audacity (https://www.audacityteam.org/) is an audio recoder/editor.
+# This script _r_enumbers _l_abels in Audacity.
+# Usage: muxsa-rl labeltext,labeltext,labeltext,...
+#   where labeltext is 
+#       - an integer, which will be padded with zeros to four digits
+#       - two integers separated by minus, which will be considered as a range
+#       - one integer followed by * and text, will set so many labels to text
+#       - any other text, which will be copied verbatim
+#
+# Example: muxsa-rl 0,5-7,42,END
+#   will set the first label in Audacity's label track to "0000",
+#   followed by "0005", "0006", "0007", "0042", and "END"
+#   
+# NB: this script assumes that muxsa-vr is running in another shell,
+# to capture Audacity's scripting replies
