How to download and modify CYGWIN and AUTO.
(This works on WINDOWS xp Home Edition running on a SONY VAIO.)
Notes by RHR and DVR 10-28-02.

Step 1:  Download cygwin (a version of unx that runs in windows) and install it.
 http://www.cygwin.com
Be sure to include BASE, DEVEL, INTERPRETERS and XFREE86 trees in the setup menu.

Step 2:  Download AUTO and install it.
file "auto2000-0.9.7.zip"  from
http://sourceforge.net/project/showfiles.php?group_id=21781

Step 3.  Modify 2 AUTO files:
<Auto_dir> means whatever directory you unpacked the Auto distribution in.

1).  To the file <Auto_dir>/auto/2000/include/auto_c.h
After the line: "#include <string.h>" you should add the 
line: "#include <sys/time.h>"
This change should allow Auto to compile.

2).  To get the demos to work, you need to put a slight modification in the script file that initializes 
Auto environment variables.  In the file
<Auto_dir>/auto/2000/cmds/auto.env.sh
comment out the line: AUTO_DIR=$HOME/auto/2000
and add in its place:
AUTO_DIR=<Auto_dir>/auto/2000
You can get directories on your hard drive with the following construct: (to get c:\windows, for example);
/cygdrive/c/windows

Step 4.  Compile AUTO

In /auto/2000 give the commands:
./configure
make
This should compile AUTO.

Step 5.  Run AUTO

To open xwindows, start your session with:
source startxwin.sh
Then start Auto with the command  
source auto.env.sh

There is a directory in the distribution called "test".  If you go in there and give the command: 
"make > TEST" it will execute 7 or 8 different tests and dump the results into the file TEST.  
There is a file in the directory indy.all which contains correct results for all of the demos, so you 
can compare with that.

Step 6.  In order to convert graphics files saved in AUTO to ps format, you need to make
a change in the file tek2ps.c.  This is explained at the end of the README file in the subdirectory
/auto/2000/tek2ps:
Change the line:
static char	def_pro[]="/home/doedel/auto/97/tek2ps/pstek.pro";
to point to the correct location of the file pstek.pro.
Then in the tek2ps subdirectory, give the command
make
