;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we
;; can fix this.
;;
+;; BS2000 support:
+;;
+;; Ange-ftp has full support for BS2000 hosts. It should be able to
+;; automatically recognize any BS2000 machine. However, if it fails to
+;; do this, you can use the command ange-ftp-add-bs2000-host. As well,
+;; you can set the variable ange-ftp-bs2000-host-regexp in your .emacs
+;; file. We would be grateful if you would report any failures to auto-
+;; matically recognize a BS2000 host as a bug.
+;;
+;; If you want to access the POSIX subsystem on BS2000 you MUST use
+;; command ange-ftp-add-bs2000-posix-host for that particular
+;; hostname. ange-ftp can't decide if you want to access the native
+;; filesystem or the POSIX filesystem, so it accesses the native
+;; filesystem by default. And if you have an ASCII filesystem in
+;; your BS2000 POSIX subsystem you must use
+;; ange-ftp-binary-file-name-regexp to access its files.
+;;
+;; Filename Syntax:
+;;
+;; For ease of *implementation*, the user enters the BS2000 filename
+;; syntax in a UNIX-y way. For example:
+;; :PUB:$PUBLIC.ANONYMOUS.SDSCPUB.NEXT.README.TXT
+;; would be entered as:
+;; /:PUB:/$$PUBLIC/ANONYMOUS.SDSCPUB.NEXT.README.TXT
+;; You dont't have to type pubset and account, if they have default values,
+;; i.e. to log in as anonymous on bs2000.anywhere.com and grab the file
+;; IMPORTANT.TEXT.ON.BS2000 on the default pubset X on userid PUBLIC
+;; (there are only 8 characters in a valid username), you could type:
+;; C-x C-f /public@bs2000.anywhere.com:/IMPORTANT.TEXT.ON.BS2000
+;; or
+;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/$$PUBLIC/IMPORTANT.TEXT.ON.BS2000
+;;
+;; If X is not your default pubset, you could add it as 'subdirectory' (BS2000
+;; has a flat architecture) with the command
+;; (setq ange-ftp-bs2000-additional-pubsets '(":X:"))
+;; and then you could type:
+;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/IMPORTANT.TEXT.ON.BS2000
+;;
+;; Valid characters in an BS2000 filename are A-Z 0-9 $ # @ . -
+;; If the first character in a filename is # or @, this is replaced with
+;; ange-ftp-bs2000-special-prefix because names starting with # or @
+;; are reserved for temporary files.
+;; This is especially important for auto-save files.
+;; Valid file generations are ending with ([+|-|*]0-9...) .
+;; File generations are not supported yet!
+;; A filename must at least contain one character (A-Z) and cannot be longer
+;; than 41 characters.
+;;
+;; Tips:
+;; 1. Although BS2000 is not case sensitive, EMACS running under UNIX is.
+;; Therefore, to access a BS2000 file, you must enter the filename with
+;; upper case letters.
+;; 2. EMACS has a feature in which it does environment variable substitution
+;; in filenames. Therefore, to enter a $ in a filename, you must quote it
+;; by typing $$.
+;; 3. BS2000 machines, with the exception of anonymous accounts, nearly
+;; always need an account password. To have ange-ftp send an account
+;; password, you can either include it in your .netrc file, or use
+;; ange-ftp-set-account.
