Short: Using stdin/stdout with CLI-prgs for pipes

NAME
StdIO-Handler - Handler for StdIO access
FUNCTION
In december 1994 I got a PIPE package and I was very supprised about the
easy implementation of these pipes. So I used this very often with gzip
and tar. But after some tries, to use the pipes with standard Amiga CLI
programs, I found no trick to redirect the input and output to the pipes.
At this point I had a idea of writing a transparent handler. Thus the
StdIO-Handler was born, using some example code from the Device-Handler
by Matthias Scheler and Marius Gröger (Thanks for the available code !).
The only thing you have to do, is to copy the STDIO file to your
Devs:DosDrivers/ directory and the handler to your L: directory.
After this you can use it like all other devices.
Note: If you use this handler with the pipes, you can't use tools, which
Seek's in the files (see the appropriate pipes doc) !
Example Mount File :
/* Standard-IO Handler */
Handler = L:StdIO-Handler
Stacksize = 1000
Priority = 5
GlobVec = -1
EXAMPLES
Output the current direcory in sorted order :
List | Sort Stdio: to Stdio:
Output all files and subdirs last modified on august 1994 :
List ALL | search stdio: Aug-94 NONUM
List ALL | search stdio: -s--rw-d NONUM
