+MusE midi event scripting format 0.5
+
+Some information for the budding script writer, here is some info
+about the format currently used.
+
+Scripts can be put in two different dirs.
+<install_path>/share/muse/scripts
+for scripts bundled
+or $HOME/.muse/scripts
+for user created scripts
+
+There are two main requirements on scripts.
+
+1. a script must have the executable flag set, that is, it must be considered
+an executable from the perspective of the operating system.
+2. a script shall take an input file as argument and will update this
+file with the sought output.
+
+The tags that may occur in the file sent to the script are:
+PARTLEN <len in ticks>
+BEATLEN <len in ticks>
+QUANTLEN <len in ticks>
+NOTE <tick> <pitch> <len in ticks> <velocity>
+CONTROLLER <tick> <a> <b> <c>
+
+PARTLEN, BEATLEN and QUANTLEN are there for informational purposes, to
+make some transformations possible. e.g. quantization, beat delay.
+
+NOTE and CONTROLLER are the ones that are read back into MusE when the filter
+stops executing. These may be manipulated, removed or multiplied as seen
+fit by the filter.
+-- Note that it is a good idea to just pass on the lines your script is not
+interested in, otherwise data may unintentionally be removed --
+
+A short example in pyton that does nothing but pass on output from input
+to output is available in script DoNothing
