				Izo v2.0       
	
	This program is a 'chemistry class toy' (if we can talk of such a 
thing...). You can easily create chemical compounds, modify them and and see 
what they really look like (as a molecular model).
	As a limitation, only non-cyclic hidrocarbonated compounds are 
implemented. Thus you can't manipulate arhenes and cyclic compounds.
	The maximum number of C atoms is 15 (the molecular model doesn't look 
nice for more) and you can define up to 2 non-simple links (double or triple) 
between atoms of carbon.
	The menu is very simple to use, all functions having the ordinary 
meanings. However, if you don't know what a certain function does, just make a 
right click on it and an explaning window will pop up. Most of the functions 
also have hot-keys, but is far more confortable using the mouse only. 
	Only one library of compounds can be active at a time (the 'working' 
library). It can be either loaded from disk or created during the current 
session, by adding the compounds one by one with the Edit/Create command and 
then modifying them. The name of the working library is displayed on the menu 
bar just after the separation line and it can be changed. When saving, this 
name will be used, adding the extension '.izo'. If a previous version of the 
library is on the disk, it will be overwritten.
	On the right side of the menu bar there are two numeric fields which 
mean :
		<current index>/<total compouns>
	The current index can be changed either by the +/- commands or by 
editing.
	A compound can be represented as a molecular model (3d) or as a 
structural formula (2d). When in 3d mode you can rotate the model by mouse 
movement, while when in 2d mode you can modify the compound (add/remove atoms, 
modify links).
	A name is generated for standard compounds (there is no library of 
names or compounds except the user-created ones). It is displayed in 3d mode, 
at the bottom of the screen.


	And here's how to use the mouse with Izo v2.0 :

 Click on               Left click                      Right click             

 Menu command           Execute                         Help
 Menu field             Edit                            Help

In 2d mode :
 
 Near unsaturated
C atom                  Add methyl                      -
 Methyl                 Remove                          -
 Link                   Change (if possible)            -
 
In 3d mode :   

 Molecular model        Enter animation mode (Click again to exit) 
 Compound name          Edit
