It occurred to me that if we are going to be posting pgp'ed files to a
newsgroups it might be best to remove the PGP headers and make the
ciphertext look more text-like.  So here is some code to do that, sort of.
Basically I kept it simple so it's easy to read.

To make this:

type "st e < infile > outfile"

And to convert it back type "st d < infile > outfile"

ST.C:

#include <stdio.h>
#include <time.h>
#ifdef MSDOS || __OS2__
#include <stdlib.h> // for exit()
#endif
void
main(int argc, char **argv)
{
    int         i = 0, j = 0, k;
    char        c;
    if (argc > 2)
    fprintf(stderr, "\nUsage: %s [e|d] < infile > outfile\n", argv[0]), exit(1);
    srand(time(0));
    while (!feof(stdin)) {
        if (toupper(*argv[1]) == 'E') {
            k = rand() % 5;
            for (i = 0; i < k + 1; i++, j++) {
                if (!(j % 50)) putchar('\n');
                c = getchar();
                if (c == '\n') printf("..");
                else putchar(c);
            }
            putchar(' ');
        } else if (toupper(*argv[1]) == 'D') {
            switch (c = getchar()) {
                case ' ':
                case '\n':
                    break;
                case '.':
                    if (i == 1) putchar('\n');
                    i = !i;
                    break;
                default:
                    putchar(c);
                    break;
            }
        } else
        fprintf(stderr, "\nUsage: %s [e|d] < infile > outfile\n", \
                argv[0]), exit(1);
    }
}
