Sortail

Sortail

How would one feel when u type a nice post , and then accidentally hit
some combination of keys in Frontpage and suddenly as if struck by a
lightning , everything that u have typed till then vanishes into thin
air like smoke...Well, believe me, it doesn't feel goood.
That was exactly what happened when I was mid-way through typing the
first and now dead version of this post about Sortail, a program to
remove repetitions in the output file produced by "Email Ripper". By
the way , what is "Email Ripper" ? To know that u must see the post
below....
This code is not entirely pretty... but still to use for a while its is ok...
When on earth shall I learn to write K&R - style C-programs ..... ?
Only God and my Ma Knows :-(
Anyways, have a look guys, after all it works...
