9e still works.  it prints some
warnings about making directories
that already exist, but other than that
it's fine.

are you forgetting to gunzip first?

from the code:

                /* The following array declarations and backreferenced
                #defines is one way to fake Forth's
                        VARIABLE <name> <number> ALLOT
                in C.                                           */

    byte    path[TOKENSIZE], perms[TOKENSIZE], capes[TOKENSIZE],
            owner[TOKENSIZE], size[TOKENSIZE], spam[TOKENSIZE];

    byte  buffer[READSIZE];

    #define path    (int) & path
    #define perms   (int) & perms
    #define capes   (int) & capes
    #define owner   (int) & owner
    #define size    (int) & size
    #define spam    (int) & spam
    #define buffer  (int) & buffer

this code casts a pointer to an integer -- never do this.  just
how portable will the cast be?  take the alpha for example:  it
has 32 bit ints and 64 bit pointers IIRC.

It seems to have many bugs.

For example, it uses access permission 0 when it makes a directory.

  void mkdirs()
  {
    ...
    made = mkdir((byte *)path, 0);
    ...
  }

All sequent mkdir() for any subdirectories will fail because search
permission will be denied for a component of the path prefix.

And if that doesn't do it for you, I have a little utility I use
on Solaris (should work unchanged on any UNIX-based system);
send me e-mail if you need it.

ftp://linux01.gwdg.de/pub/cLIeNUX/interim/p9unpack.c

is for the main Plan9 50 meg package, on Linux. Is that "wrap" ?

Is there a tool (for UNIX) to look at the contents of wrap bundles?
It seems that 9e (did work once some time ago, no more) and unwrap
(perl script, never worked except printing file names and creating
directories).
