			CYGWIN specific instructions

Refer to http://sourceware.cygnus.com/cygwin/ to properly install CYGWIN:

   - if you use the last installation version (installs /bin /usr /etc ...)
     you should not have problems.

   - for old installation version (which installs cygwin in something like 
     c:\CYGNUS\CYGWIN~1\H-I586~1\BIN) you surely have to update cygwin1.dll
     (see cygnus doc). Do not forget to create /bin (containing a sh.exe) 
     and /tmp. You can define /usr/local/... subdirectories to contain 
     installed Unix-like commands.

It is a good idea to defined a /home/<username> directory and to define the
HOME environment variable. If you use MSVC++ it is pertinent to set MSVC++
environment variables (generally MSVC++ generates a .bat file to define them,
on my system it is called c:\vcvars32.bat). You can also use RXVT, which is a
graphical environment for bash (however, you should also keep your MSDOS bash
since GNU-Prolog line-editor does not work well under RXVT in console
mode). The version of RXVT I use is 2.7.2, for more information consult
http://www.rxvt.org/distribution.html.

Personnaly, I have 2 versions of the cygnus shell:

   - a MSDOS console shell (called cygnus_msdos.bat)
   - a RXVT  console shell (called cygnus_rxvt.bat)

Here is my cygnus_msdos.bat file (to launch bash under a MSDOS console):

@ECHO OFF
SET MAKE_MODE=UNIX
SET HOME=c:\home\diaz
SET PATH=c:\bin;c:\usr\local\bin;%HOME%\bin;.;%PATH%
call c:\vcvars32.bat
bash

Here is my cygnus_rxvt.bat file (to launch bash using RXVT):

@ECHO OFF
SET MAKE_MODE=UNIX
SET HOME=c:\home\diaz
SET PATH=c:\bin;c:\usr\local\bin;%HOME%\bin;.;%PATH%
call c:\vcvars32.bat
rxvt -fn "Courier-bold-12" -tn xterm -sl 250 -e bash

NB: DO NOT define the CYGWIN environment variable with 'tty' inside if you want
to run a cygwin compiled version of GNU-Prolog.

For information here is my $HOME/.bashrc file:

export PS1='\w> '
export TERM=linux
stty intr ^c susp ^z start ^q stop ^s quit ^\\ erase ^?
alias ll=ls\ -l
alias more=less
alias ls=ls\ -F\ --color

Finally note that a version of Emacs exists for winXX machines. Refer to
http://www.cs.washington.edu/homes/voelker/ntemacs.html for more information.
