Instead of ``ed' one can use ``ex'' which should be in any distribution as
its part of ``vi'' or ``vim''.  I think the command set of ``ed'' is a
subset of ``ex'' so scripts should work the same.

I frequently use the gnu shtool program for this sort of thing unless the
job is very simple, and I really want to edit the file in place.

The stamping of paper is an operation so much easier than the laying of
taxes, that a government, in the practice of paper emissions, would rarely
fail, in any such emergency [such as an election], to indulge itself too
far in the employment of that resource... -- Alexander Hamilton
