#automatic collection of dependencies in the source files.
#it's only updated the first time, after that it must be done maually
#with "make depend"
#the dependecies are included from a separate file:
-include dependencies.in
#target to update the file, it's removed first
depend: rmdepend dependencies.in
#remove the file
rmdepend:
	rm -f dependencies.in
#build the file that contains the dependencies. no deps in this rule.
#if there were deps it would be rebuilt every chnage, which is unneded:
