The program is supposed to echo stdin to stdout if the program name
starts with 'e'. This was only possible if one do something like:
PATH=$PATH:.
echo '5*5+17' | eprog
because otherwise the first char would be '.' not 'e'.
This was done by using basename(3) and -include libgen.h (in the
Makefile so as to not modify the code more than is necessary).
The Makefile now copies 'prog' to 'eprog' and 'prog' to 'calc'. It also
copies 'prog.alt' to 'eprog.alt' and 'ecalc.alt' as this is what the
program is documented as.
Format fix the calc.1 man page and remove calc.man. This is so that the
formatting is correct and also so as to not have to maintain more than
one copy of the same text (which was almost certainly already out of
sync as I did not update calc.man when I added calc.1 exactly for the
reason that I deleted calc.man).
The try.sh script has been updated and so has the try.this.txt file that
try.sh uses.
This should complete the review of 2015/burton if I'm not very much
mistaken.
Format fixes (maybe typos?) in README.md.
Added calc.1 which is essentially what was calc.man but so one can
actually get expected formatting when using man ./calc.1. If I fixed any
typos they are not fixed in calc.man. I kept the commands the same so
one would have to change calc to ./prog.
Formatting and maybe typos in road.to.obscurity.
