+This is a prelodable shared library that provides SMB client services
+for existing executables. Using this you can simulate a smb
+filesystem.
+
+Currently this code only works on Linux with glibc2. Eventually I hope
+to make it portable to lots of OSes but at the moment if you don't
+have Linux then don't even try to use it.
+
+To use it you need to do this:
+
+export SMBW_USER=username
+export SMBW_PASSWORD=username
+export LD_PRELOAD=full_path_to_smbwrapper.so
+
+then try to access /smb/SERVER/SHARE/ and see what happens.
+
+For debugging you can set SMBW_DEBUG to an integer debug level.
+
+This is code under development. Lots of things don't work yet. Quite a
+few things do though, for example I've successfully run tar, less, ls,
+bash, cmp, cat, du and a bunch of other utilities on files accessed
+via this library.
+
+If you want to help with the development of this code then join the
+samba-technical mailing list.
