bfc.exe - BF to C compiler

   bfc

      Compile BF program specified in stdin, write output to stdout.

   bfc <infile>

      Compile BF program specified in <infile>, write output to
      stdout.

   bfc <infile> <outfile>

      Compile BF program specified in <infile>, write output to
      <outfile>.

   Data tape size of output program is specified at compile time
   (0x10000), code size is unlimited.  Output C source is also a valid
   BF program, furthermore:

      ./bfc prog.bf
      ./bfc prog.bf | ./bfc
      ./bfc prog.bf | ./bfc | ./bfc

   ... will all produce the exact same output.

   If data pointer move outside of tape range, the behavior is
   undefined.  Output C code does include an exception handler, but
   that's not always helpful.  To be sure that the BF program will not
   overflow/underflow the data tape, run the code with an interpretor
   first.

bfi.exe - BF interpretor (C version)

   bfi

      Run BF program specified in stdin, write output to stdout.

   bfi <prog>

      Run BF program specified in <prog>, reading input from stdin,
      writing output to stdout.

   bfi <prog> <infile>

      Run BF program specified in <prog>, reading input from
      <infile>, writing output to stdout.

   bfi <prog> <infile> <outfile>

      Run BF program specified in <prog>, reading input from
      <infile>, writing output to <outfile>.

   Code and data tape sizes are specified at compile time (0x10000).
   If BF program exceeds those limits, interpretor will terminate with
   error message.

   Because the interpretor optimizes code at load time, the amount of
   space available for code is often more than 0x10000.  To check how
   much code/data space is needed, run the Perl version of the
   interpretor.

bfi.pl - BF interpretor (Perl version)

   Command line arguments are the same as the C version.

   The Perl version supports infinite code/data tapes, which grows
   dynamically as the program uses them.  At exit, interpretor will
   print out the size of code (optimized/unoptimized) and data tapes
   required to run the program.

   This version also includes an infinite loop check.  If an infinite
   loop is detected, program will terminate early with error message.
   Works for most programs but not all, read the source for details.
