-  パスワードは、smbclient の -A オプションを使えるなら、
-  smbclient -A ~/.w3m/smb として、使えない場合は ~/.w3m/smb を
-  読んで環境変数 PASSWD で渡します。
+  パスワードは、
+  1) ~/.w3m/smb にパスワードが設定されており、
+     smbclient の -A オプションを使えるなら
+     smbclient -A ~/.w3m/smb として渡します。
+  2) 環境変数 PASSWD_FILE (パスワードのみのファイル)が設定

+  3) ~/.w3m/smb にパスワードが設定されていれば、
+     環境変数 PASSWD_FD を使って標準入力経由で渡します。
   どちらにせよ、あまり良い事ではないので SMB(CIFS)プロトコルを
   喋る版を希望。

 smb.cgi
 
   [w3m-dev 03634] smb.cgi
   localcgi to access SMB.
   Since it uses nmblookup, smbclient, you should install samba.
-  Password can be configured in ~/.w3m/smb:
-     when -A option available smbclient -A ~/.w3m/smb 
-     otherwise, environment variable PASSWD 
-		  that is set by contents of ~/.w3m/smb
+  Password can be passed to smbclient:
+  1) When the password is set by contents of ~/.w3m/smb and
+     -A option available, `smbclient -A ~/.w3m/smb' is used.
+  2) When the environment variable PASSWD_FILE, it is used.
+  3) When the password is set by contents of ~/.w3m/smb,
+     the password is passed via standrad I/O using
+     the environment variable PASSWD_FD.
