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.
