29 ;;; This package is for running a remote compilation and using emacs to parse
30 ;;; the error messages. It works by rsh'ing the compilation to a remote host
31 ;;; and parsing the output. If the file visited at the time remote-compile was
32 ;;; called was loaded remotely (ange-ftp), the host and user name are obtained
33 ;;; by the calling ange-ftp-ftp-name on the current directory. In this case the
34 ;;; next-error command will also ange-ftp the files over. This is achieved
35 ;;; automatically because the compilation-parse-errors function uses
36 ;;; default-directory to build it's file names. If however the file visited was
37 ;;; loaded locally, remote-compile prompts for a host and user and assumes the
38 ;;; files mounted locally (otherwise, how was the visited file loaded).
40 ;;; See the user defined variables section for more info.
42 ;;; I was contemplating redefining "compile" to "remote-compile" automatically
43 ;;; if the file visited was ange-ftp'ed but decided against it for now. If you
44 ;;; feel this is a good idea, let me know and I'll consider it again.
48 ;;; To use rcompile, you also need to give yourself permission to connect to
49 ;;; the remote host. You do this by putting lines like:
54 ;;; in a file named .rhosts in the home directory (of the remote machine).
55 ;;; Be careful what you put in this file. A line like:
59 ;;; Will allow anyone access to your account without a password. I suggest you
60 ;;; read the rhosts(5) manual page before you edit this file (if you are not
61 ;;; familiar with it already)
67 ;;; The following should not be needed.
