- ;;; PC support for efs
- ;;;-----------------------------------------------------------------
-
- ;;; Works for the DOS FTP servers:
- ;;; Novell LAN WorkPlace v4.01 (NetWare & EXOS)
- ;;; PC/TCP Version 2.05 pl2 FTP Server by FTP Software
- ;;; Microsoft FTP Server service (beta 2)
- ;;; NCSA DOS ftp server.
- ;;; Frontier Technologies super tcp server (runs under MS WINDOWS)
- ;;; Alun's Windows FTP daemon for Winsock, v1.8b
- ;;;
- ;;; Works for IBM OS/2 TCP/IP FTP Version 1.2
-
- ;;; Currently support for all of the above FTP servers are in this file.
- ;;; Should they live in separate files?
-
- ;;; host and listing type hierarchy in this file
- ;;;
- ;;; dos: dos:novell, dos:ftp, dos:ncsa, dos:microsoft, dos:stcp, dos:winsock
- ;;; os2:
-
- ;;; DOS and OS/2 have slightly different filename syntaxes.
- ;;;
- ;;; DOS only allows at most one extension (".") per filename.
- ;;; A directory name usually has the extension ".DIR" implicit, but
- ;;; it seems that other extensions can be used.
- ;;;
- ;;; OS/2 running the FAT file system uses the same 8.3 format for
- ;;; filenames as DOS, except that extensions are allowed in directory names.
- ;;; OS/2 running the HPFS (high performance file system allows an arbitrary
- ;;; number of extensions in a filename.
- ;;; Mostly these differences are unimportant here, except in the dos
- ;;; definition of efs-allow-child-lookup.
