-ENVIRONMENT VARIABLES
----------------------
+OPTIONS
+-------
 
-SMBW_USER
- This is usually set by smbsh but you can set it manually. It
- specifies the username you will connect to servers with.
+-U username
+   specify the username and optional password (as user%password)
 
-SMBW_PASSWORD
- This is usually set by smbsh but you can set it manually. It
- specifies the password used to connect to smb servers.
-
-SMBW_DEBUG
+-d debug level
  This is an integer that controls the internal debug level of smbw. It
  defaults to 0, which means no debug info.
 
-SMBW_LOGFILE
+-l logfile
  The place where smbw debug logs are put. If this is not set then
  stderr is used.
 
-SMBW_PREFIX
+-P prefix
  The root of the SMB filesystem. This defaults to /smb/ but you can
  set it to any name you like.
 
-SMBW_WORKGROUP
+-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
