0100 # Generating Prerequisites Automatically.  The g++ compiler has an
0101 # option -M or -MM to write to standard output a list of dependencies
0102 # based on the #include statements.  The "sed" adds the dependency
0103 # file itself as a second target.  The result is a mini-makefile which
0104 # specifies the .o and .d files as targets which depend on all the
0105 # files found through the #include statements.  This file is then
0106 # included, causing GNU Make to honour these dependencies.
0107
0108 # The "set -e" causes the shell to exit with an error when the "g++"
0109 # fails (otherwise it would only notice the last command in the
0110 # pipeline, namely "sed").  GNU Make notices the error and exits
0111 # sooner than it otherwise would (still not as soon as I expect,
0112 # though!).  Even then, an empty file is made, so "[ -s $@ ] || rm -f
0113 # $@" removes it ([ -s filename ] gives zero exit code only if file
0114 # exists and has a size greater than zero).  This avoids making
0115 # corrupt .d files which would play havoc with your next build.
