Well, I suppose it's a matter of opinion whether that's an easy way to
solve the problem.  It requires a lot of keyboard input.  Here's one
which I would use.  To compile, just:

$ cc stripcr.c -o stripcr

It's a filter: that is, you run it like this:

$ stripcr <infile >outfile

The reason for this isn't laziness: that way, you can pipe things into
it.

stripcr.c:
----------------------------------------------------------------------
#define LINELENGTH 8192					    /* max length of program line */
#include <stdio.h>

char inbuffer [LINELENGTH];				    /* read in here */
char outbuffer [LINELENGTH];				    /* write from here */
int main (int argc, char *argv [])
{
  while (fgetsb (inbuffer, LINELENGTH, stdin))
    {
    char *i = inbuffer;
    char *o = outbuffer;

    do
      {
      if (*i != '\r')					    /* not a CR */
	*o++ = *i;					    /* copy it */
      }
    while (*i++);
    fputs (outbuffer, stdout);
    }
  }
