After uncompressing and extracting the auto files from auto.tar.Z move the
auto directory created to its installed place (ie /usr/auto).

The standard Linux shell (bash) does not work with AUTO. The best option
is to use the C-shell which AUTO expects. If bash must be used then all
references to the environment variable AUTO_DIR must be deleted from the
source code and script files and the name of the auto directory
hard-wired in.

To set tcsh as your shell edit /etc/passwd as root and change 'bash' to
'tcsh' on the line corresponding to your login. Add the following lines to 
.cshrc in your home directory
	setenv AUTO_DIR *path_to_auto*/auto/97
	set path=($AUTO_DIR/cmds $AUTO_DIR/bin $path)

To use bash add the following lines to your .login
	source *path_to_auto*/auto/97/cmds/auto.env
Change cmds/auto.env so that the AUTO_DIR variable is hardwired in
	setenv AUTO_DIR *path_to_auto*/auto/97
Change every occurence of $AUTO_DIR in the script files in auto/97/cmds to
the AUTO path. In gui/auto97.c change every occurence of
	copyenv(AUTO_DIR)
to the auto path in speech marks i.e. "/auto/97/"
and every occurence of 
	$AUTO_DIR/
to the auto path i.e. /auto/97/

In auto/97/gui/sun.makefile add the option -traditional to compiler
options
	CC = cc -O -traditional
On a standard Linux system the INC_DIR should be set to
	INC_DIR=/usr/X11/include
and LIB_DIR should be set to
	LIB_DIR=/usr/X11/lib
This assumes that the Motif header and library files have been installed
in the standard places. They have been if there is a directory
/usr/X11/include/Xm. If they are in a different place it is probably
easiest to place links in the X11/include and X11/lib directories.
Motif is a commercial product and vendors can be contacted on the web.

Change all occurences of dreal to DFLOAT in auto/97/src/autlib1.f
If the fortran compiler command 'f77' is not installed on the machine then 
install f2c and its libraries so the compiler is available.
The precompiled f2c package can be downloaded from
ftp://sunsite.unc.edu/pub/Linux/devel/lang/fortran/f2c-960717.elf

In tek2ps/tek2ps.c change the definition of 'def_pro' at line 25 to the correct
path for auto.
In directory tek2ps type 'make' to build the program tek2ps 

In auto/97/ type 'make' to make the the complete system.

AUTO was built using version 2.7.2 of gcc on version 2.0.0 of the Linux
kernel. On Linux kernel 1.2.13 and gcc 2.6.8 this procedure does not work.
