This version will *unpack* some sharfiles successfully.
If anybody can fix the problem with the SED command line
creation, it'll make a sharfile.
Cheers! -- Jim O.

Revision History:
88/01/26 Porting begun for OS-9 6809 by Jim Omura. So far
this is a *partially* working version of Shar.
It will unpack a "shar"file created by the 68K version, and
many other Sharfiles, but it will not create one successfully.
The SED command lines are not being set correctly. I have noticed
that many "variables" have been declared in "constant" form by
Wecker, and I've converted some of them. This may be where
the problem lies. Look first to converting the declarations
in 'shar.h'.
Compiler Usage:
If you do not have 'make' you will have to add
#define OS9
to the top of 'shar.h'. If your 'make' utility defaults
to defining OS9, you should remove the '-dOS9' from the
CFLAGS variable in the 'makefile'.
87/05/22 Patch by Dieter Stoll to fix 'mkdir' error report.
General:
This is an early version of Wecker's Shar.c with "first stage"
porting to OS-9 68K completed. Use the Unix instructions for now.
The code should be redone in some areas for cleaner logic, but
has been tested and will create a 'shar' file. Furthermore, it
will unpack many types of shar files. The only problem I've
uncovered is that it will overwrite existing files without giving
an error.
Many thanks to Gary Kendall without whom I would have abandonned
the effort.
Cheers! -- Jim Omura
The following are all the instructions I received:
Creating a shar file:
AMIGA: shar >foo.shar -a makefile *.h *.c
VMS: create a batch job that executes:
$ shar -a makefile *.h *.c
edit the batch .LOG file (which is your shar file)
U**X: shar -a makefile *.h *.c >foo.shar
(P.S. the -a switch means do all options)
Extracting from a shar file:
AMIGA: shar -u foo.shar
VMS: shar -u foo.shar
U**X: shar -u foo.shar or sh foo.shar
Installation:
NOTE: The following will no longer work because I have broken
the program down into smaller source modules. I have
included these installation instructions to help in the creation
of the necessary 'makefile's. -- Jim O.
AMIGA: cc -DAMIGA shar.c
ln -o shar shar.o -lc
VMS: cc/DEFINE=VMS shar.c
link shar,sys$library:vaxcrtl/lib
shar :== $dev:[dir]shar
U**X: cc -O -DULTRIX -o shar shar.c -lc
Just typing "shar" will yield a usage line. (Doc: thanks for the code to
base this off of).
