Well, we *can* assume that CSplit is available, but I wouldn't want to make
this into a two-step process.  That means that requirements 3&4 are
basically, "Oh, and make sure CSplit is called behind the
covers."  It would be nice to do this without the use of a temp file.

What this may mean is completely overtaking CSplit, writing it as a general
output stream handler such that we could basically putsToCSplit(), and it
would handle its own state information.  CSplit's main() routine could
almost be written, then, something like:

int main(int argc, char** argv)
{
 /* parse args */

 CSPLIT* handle = CSplitOpen(outputfile, len_of_file, width_of_file);
 FILE* input = fopen(inputfile, "r");
 char buffer[512];

 while (fgets(buffer, sizeof(buffer), input) != NULL)
 {
  CSplitPrintf(handle, "%s", line);
 }
 CSplitClose(handle);
 fclose(input);

 return 0;
}

Of course, with more error checking.  :-)  Maybe this could be step #1 in
the challenge?
