-## Makefile to build C example programs included with the COCO distribution
-##
-## NOTE: We have tried to make this Makefile as generic and portable
-## as possible. However, there are many (incompatible) versions of
-## make floating around. We regularly test using GNU make and BSD make
-## from FreeBSD. If you have trouble compiling the examples, please
-## try to use GNU make. 
-##
-## On Windows it is best to use either the included NMakefile by running
-##
-##   nmake -f NMakefile
-##
-## or installing Cygwin and running GNU make from within Cygwin.
