"m4orch" expands orchestra files that incorporate macros  and entire
instruments defined in the Eastman Orchestra Library.
For example, the following SETUP macro
	SETUP(44100,2205,1) 
will be expanded to :
		sr = 44100
		kr = 2205
		ksmps = 20
		nchnls = 1
Each call to an instrument within the Eastman Csound Library
must be made in caps on a separate line: Thus, a complete mono
orchestra file using library instruments "marimba" and "drums"
looks like this:
		SETUP(22050,2205,1) 
		MARIMBA 
		DRUMS 
Csound code can be added to the ends of library instruments by enclosing
the added code in parentheses and square braces :
		SETUP(22050,2205,1) 
		USEOLIB 
		MARIMBA([outs sqrt(p9)*a1, sqrt(1-p9)*a1])
NOTE : If you use any ECMC Csound Library macros, YOU MUST FIRST RUN THE
JOB THROUGH THE ORCHESTRA PREPROCESSOR "m4orch," which expands these
macros.  
	"m4orch" (which may be abbreviated "m4o") writes the expanded
version of your input file into an output file called "orch.orc". This
file (or its abbreviation "orc") can then be used as your orchestra file
input to csound.

	The complete process then becomes :

(1)	m4orch orchestrafile
(2)	score11 scorefile
(3)	csound (- options) orch.orc sout   **or**  cs (- options) orc sout
