Having the first line of a file tell how to process it is a nice idea
because it is a self documenting process.  It does not, however,
explain the relationships between that file and others it goes along
with.  For example, conditional compilation in C with one particular
flag (e.g. -DHOHO) often applies to more than one source file at a
time.  Thus to be fully self documenting, each of those files must
note that they are associated with all of the others, and if one is
processed with -DHOHO, the others have to be also.  Sounds pretty
awkward to me.

This is exactly one of the situations that make handles.  Seems like a
better idea when distributing files to distribute their makefiles also
so others can see not only how to process the file but how it relates
to other files.
