SALES TALK
        If you have one or more magtape units and want to do more with
them than just run  `tar', this is for you.

        On the shell level this package offers programs for
  - getting a quick look at a tape,
  - making exact copies of tapes even if you've got only one magtape unit,
  - extracting arbitrary portions from tapes and
  - the reading and writing of ANSI standard labelled tapes.
All these programs work equally well on real tapes and on tape images
on disk.

        On the C-level it supplies routines for handling real tapes and
tape images on disk as a unified concept (`generalized magtape').


INSTALLATION
-       Take a look at the file  `tploc.h'  which requires you to define:

        SYSCODE                         the name of your installation
        DEV_LOW, DEV_NORMAL, DEV_HIGH   the name(s) of the magtape unit(s)

        You may also #define one of the following flags to describe
        the reading and writing of the tape:
        NORMAL (default)                anything goes (VAX, etc)
        EVEN                            only even blocksize allowed (PDP11)
        SWAB                            bytes must be swapped (M68000)

        If you are not on a UNIX(like) system, you may look at `sys.c',
        which contains the (non-magtape) interface to the OS.

-       Call  `make all'  and the shell commands as described in mag(1)
        will appear.

-       To install the shell commands, change the macro USR (and possibly
        BIN, LIB, and INC) in the  `makefile'  and do  `make install'. To
        install the C-routine library  `libt.a', do  `make libt'.

-       Now do

                ansir -fp test.image

        to get a feel for what it does. (Then do it a second time!).

CYBER
        If you happen to have a Control Data Cyber around, running
SCOPE or NOS/BE, call  `make NOS'  to get  `NOSsplit', a program for
reading Cyber SI-format tapes, and  `NOStr'  which converts from various
Cyber character codes.
