;;; Commentary:
;; This package is for running a remote compilation and using emacs to parse
;; the error messages. It works by rsh'ing the compilation to a remote host
;; and parsing the output. If the file visited at the time remote-compile was
;; called was loaded remotely (ange-ftp), the host and user name are obtained
;; by the calling ange-ftp-ftp-name on the current directory. In this case the
;; next-error command will also ange-ftp the files over. This is achieved
;; automatically because the compilation-parse-errors function uses
;; default-directory to build its file names. If however the file visited was
;; loaded locally, remote-compile prompts for a host and user and assumes the
;; files mounted locally (otherwise, how was the visited file loaded).
;; See the user defined variables section for more info.
;; I was contemplating redefining "compile" to "remote-compile" automatically
;; if the file visited was ange-ftp'ed but decided against it for now. If you
;; feel this is a good idea, let me know and I'll consider it again.
;; Installation:
;; To use rcompile, you also need to give yourself permission to connect to
;; the remote host. You do this by putting lines like:
;; monopoly alon
;; vme33
;;
;; in a file named .rhosts in the home directory (of the remote machine).
;; Be careful what you put in this file. A line like:
;;
;; +
;;
;; Will allow anyone access to your account without a password. I suggest you
;; read the rhosts(5) manual page before you edit this file (if you are not
;; familiar with it already)

(provide 'rcompile)
(require 'compile)
;;; The following should not be needed.

;; Better would be, if there are functions to provide user, host and

;; The function calls are wrapped by `funcall' in order to pacify the byte
;; compiler. ange-ftp check removed, because it is handled also by Tramp.
