			Chemtool Version 1.1.1

-------------------------------------------------------------------------------

Thomas Volk	12.Mar.1998

Chemtool is a program for drawing organic molecules easily and store them as
a X-Bitmap file. It runs under X-Window and is written with the Athena
Widget Set. 


----------------------> Usage:

This program is very simple to use. You can find out the most things 
by your self. 

Draw Bounds:

Bounds can be drawn in 4 various angle types (hexaeder 60 ,
two pentaeder 72 and 45 styles).

Insert Text:

Into the big text-insert box you can write text that will 
be insert in the graphic. You can insert text with a 
left/middle/right alignment. There are two special chars 
in the text-insert function:

		'^' to shift up 	(eg N^+)
		'_' to shift down	(eg CH_3) 

Center:

If there is not enough space for your molecule you can
put it in the middle of the sheet with the center button.

Export:

You can export your molecules as X-Bitmap, XFig-file or
in the PicTeX format. The PicTeX output depends on the
fig2dev program witch is included in the transfig 
package.
You can create the outputs in 3 different sizes, witch
depends on the chosen zoom-factor.
To include the PicTeX-file in your LaTeX-Document you 
need the pictex-macro of your latex distribution. 

Hotkeys:

One hotkey is inserted: while you drawing bounds, you can
can insert text by typing the 't'.



----------------------> Installation:

To build Chemtool type:

		xmkmf
		make
		make install 


----------------------> Dependencies:

The LaTeX-output depends on the transfig package version 3.2.0
or later.

----------------------> Changes :

15.Feb.1998 	I fixed a bug that some times crashed the program down,
		if you use the functions : center and zoom.

27.Feb.1998	Another (crash)-bug was fixed.


28.Feb.1998	Adding new features :
					export to xfig and PicTeX;
					moving of objects;

12.Mar.1998	The LaTeX and xfig-output works whit 3 different
		zoom-factors.
