[Paul, this kind of question is better sent to samba at lists.samba.org,
not the admin address.]

There is an smbwrapper/README [attached] file in the source
distribution.  Note that smbwrapper will probably not work with recent
Linux distributions because the mechanism that lets it hook in has
been removed.

,----[ smbwrapper/README ]
| This is a prelodable shared library that provides SMB client services
| for existing executables. Using this you can simulate a smb
| filesystem.
| *** This is code under development. Some things don't work yet ***
| Currently this code has been tested on:
| - Linux 2.0 with glibc2 (RH5.1)
| - Linux 2.1 with glibc2
| - Solaris 2.5.1 with gcc
| - Solaris 2.6 with gcc
| - SunOS 4.1.3 with gcc
| - IRIX 6.4 with cc
| - OSF1 with gcc
| It probably won't run on other systems without some porting. If you
| have a different system then see the file PORTING.
| To use it you need to do this:
| 1) build smbwrapper.so using the command "make smbwrapper"
| 3) run smbsh
| You will be asked for a username and password. After that you will be
| returned to a shell prompt. It is actually a subshell running with
| smbwrapper enabled. 
| Now try to access /smb/SERVER for some SMB server name and see what
| happens. If you use the -W option to set your workgroup or have
| workgroup set in your smb.conf then listing /smb/ should list all SMB
| servers in your workgroup.
| -------
| -U username
|    specify the username and optional password (as user%password)
| -d debug level
|  This is an integer that controls the internal debug level of smbw. It
|  defaults to 0, which means no debug info.
| -l logfile
|  The place where smbw debug logs are put. If this is not set then
|  stderr is used.
| -P prefix
|  The root of the SMB filesystem. This defaults to /smb/ but you can
|  set it to any name you like.
| -W workgroup
|  This is the workgroup used for browsing (ie. listing machines in the
|  /smb/ directory). It defaults to the one set in smb.conf.
| -R resolve order
|  This allows you to override the setting of the name resolve order
|  from smb.conf
| -----------------
| smbwrapper does an inverse attribute maping to what Samba does. This
| means that the archive bit appears as the user execute bit, the system
| bit appears as the group execute bit and the hidden bit appears as the
| other execute bit. You can control these with chmod. The mapping can
| be enabled an disabled using the normal smb.conf controls (ie. "map
| archive", "map system" and "map hidden").
| Read-only files appear as non-writeable by everyone. Writeable files
| appear as writeable by the current user.
| ----------
| Things that I have tried and do seem to work include:
|   emacs, tar, ls, cmp, cp, rsync, du, cat, rm, mv, less, more, wc, head,
|   tail, bash, tcsh, mkdir, rmdir, vim, xedit, diff
| things that I know don't work:
|  anything executing from the share
|  anything that uses mmap
|  redirection within shells to smbsh files
| If you want to help with the development of this code then join the
| samba-technical mailing list.
