You make a text file something like this:
-----------------------------------/ cut here /------------------------------
/
|
\
-
 /
 |
 \
 -
-------------------------------------//------------------------------------
et cetera that has the animation in it.

You then have to replace the line feed characters (0x0A) with a carraige 
return character (0x0D) so that the animation will print out all on one 
line, overstriking.  The following C program will do this:

-----------------------------------/ cut here /------------------------------
/* strip_linefeed.c
 * Usage:
 * 	strip_linefeed <infile> <outfile>
 * program copies infile to outfile, replacing line feed characters with 
 * carraige return characters.
 */

#include <stdio.h>

int main(int argc, char **argv)
  {
    int i;
    FILE *IN, *OUT;

    if(argc!=3)
      {
        printf("number of args, bozo!\n");
        return(1);
      }
    IN = fopen(argv[1], "rb");
    if(!IN)
      {
        printf("file error on %s\n",argv[1]);
        return(2);
      }
    OUT = fopen(argv[2], "wb");
    if(!OUT)
      {
        printf("file error on %s\n",argv[2]);
        if(IN)
          fclose(IN);
        return(2);
      }


    while ((i=fgetc(IN))!=EOF)
      if(i!=0x0a)
        fputc(i, OUT);
      else
	fputc(0x0d,OUT);
    return(0);
  }

-------------------------------------//------------------------------------

save the program as a seperate file named strip_linefeed.c, and compile 
it with:
	gcc strip_linefeed.c -o strip_linefeed
or use whatever other c compiler is available on your system.

Hope this helps.

Not that it will help him, prolly.  I tried fingering his address, but 
apperently, his sight doesn't allow outside fingering.

*damn* security fascists.
