+To create "smbsh" on Linux, just type "make".
+
+If you execute "smbsh" in *this* directory (so that it can find the required
+shared library), you'll find yourself in a new shell. You can then issue
+commands referencing the "/smb" pseudo-filesystem:
+
+ ls /smb
+ ls /smb/WORKGROUP_OR_DOMAIN
+ ls /smb/SERVER
+ ls /smb/SERVER/SHARE
+ ls /smb/SERVER/SHARE/PATH
+
+Note that WORKGROUP_OR_DOMAIN is *not* used other than at that level. This is
+consistent with the smb:// URI definition.
+
+Usage:
+ smbsh [-L <path to find smbwrapper.so>]
+ [-p <library to load before smbwrapper.so>]
+ [-a <library to load after smbwrapper.so>]
+ [-d <debug value for libsmbclient>]
+ [-n] (do not ask for username/password)
+ [-W <workgroup>]
+ [-U <username%password]
+ [command]
+
+So to list the contents of \\MYDESK\C$ where a username (adventure) and password
+(xyzzy) are required, and with smbwrapper.so installed in /usr/share/samba, you
+could try:
+
+ smbsh -L /usr/share/samba -U adventure%xyzzy ls '/smb/MYDESK/C$'
+
+(It's a good idea to get in the habit of surrounding windows paths in single
+quotes, since they often contain spaces and other characters that'll give you
+headaches when not escaped.)
+
+This smbsh seems to work quite well on Linux 2.4 and 2.6. The biggest problem it
+has is in tracking your current working directory. I haven't had the time to
+track that down and fix it.

+/*
+ * This is a rewrite of the original wrapped.c file, using libdl to obtain
+ * pointers into the C library rather than attempting to find undocumented
+ * functions in the C library to call for native file access. The problem
+ * with the original implementation's paradigm is that samba manipulates
+ * defines such that it gets the sizes of structures that it wants
+ * (e.g. mapping 32-bit functions to 64-bit functions with their associated
+ * 64-bit structure fields), but programs run under smbsh or using
+ * smbwrapper.so were not necessarily compiled with the same flags. As an
+ * example of the problem, a program calling stat() passes a pointer to a
+ * "struct stat" but the fields in that structure are different in samba than
+ * they are in the calling program if the calling program was not compiled to
+ * force stat() to be mapped to stat64().
+ *
+ * In this version, we provide an interface to each of the native functions,
+ * not just the ones that samba is compiled to map to. We obtain the function
+ * pointers from the C library using dlsym(), and for native file operations,
+ * directly call the same function that the calling application was
+ * requesting. Since the size of the calling application's structures vary
+ * depending on what function was called, we use our own internal structures
+ * for passing information to/from the SMB equivalent functions, and map them
+ * back to the native structures before returning the result to the caller.
+ *
+ * This implementation was completed 25 December 2002.

+ * rather than using this undocumented interface, I'd sure love to hear about
+ * it. Better yet, if you can figure out where the alternate malloc()
