[ESS] .help.ESS gets appears only in certain directories

[Vitalie Spinu]

Hi Alex,

I've just committed a fix. You were unlucky to use SVN on the next day
after a major change of inferior-ess internals. Some small detail was
missing during the proc init. It's solved now. Can you please check?

As a general comment, people are highly welcome to use SVN version. More
people to use it, faster the development will go and sooner new ESS
version will see the light.

Here are very simple instructions to use SVN:

-----
1: At command prompt, switch to the directory where you would like to
keep your svn (for example "~/VC/" for Version Control)

  cd ~/VC

2: checkout ESS:

  svn checkout https://svn.r-project.org/ESS/trunk ESS

3: in your .emacs make sure emacs loads SVN version and not the
installed one. Put this before (load "ess-site.el"):

  (setq load-path (cons "~/VC/ESS/lisp/" load-path))
  
-----

Next time you would like to update to the newest version, just do

  svn update

from the ESS directory.


How about placing these (or similar) instructions on the ESS web site? 

Vitalie.
