##  Generate dependencies for INN makefiles
##
##  This shell script automates the process of updating the dependencies in
##  INN's Makefiles.  It uses gcc -MM to do this, since only the maintainers
##  should normally have to do this and using a compiler to parse include
##  directives is more reliable than more ad hoc methods.  It takes compiler
##  flags as its first argument and then a list of all source files to
##  process.
##
##  The Makefile is updated in place, and everything after "DO NOT DELETE
##  THIS LINE" is removed and replaced by the dependencies.
