Brian S. Dean fc56e6b4f9 Rearrange the pinout for the programmer to be a little more logical.
Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins.  This is important when programming the target
in-system.

Totally change the way the pin definitions are defined.  Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination.  A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.

Brian S. Dean e25bae098c Cosmetic, don't output a preceding linefeed for usage().

Brian S. Dean c06319e33c Return error codes instead of exiting, thus making sure that we exit
only via main() so that the exitspecs are properly applied.

When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.

Don't complain when an input file size is smaller than the memory size
we are programming.  This is normal.

Brian S. Dean 979d0d0254 Makefile : install the man page
main.c : drop the giant usage text now that we have a man page.

Brian S. Dean 4265bfa150 The program was getting too large for a single file. Split it up into
more modular pieces.

Also, accept command abbreviations as long as they are not ambiguous.
