+;;; 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 it's 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)
