README for Gerwin 0.6
---------------------


0. What is Gerwin?


Gerwin is a tool that aid you in creating data models and then
(perhaps) implementing it on a relational database.

You can draw your data model via an entity-relation diagram, generate
the tables from it (another graphical diagram) and then generate the
SQL or GerwinML that mirror such relational tables. Currently several SQL
dialects are supported (for most popular free software database
systems) and the GerwinML generation makes to support more targets
very easy (writing a XSL for the translation from the XML to some SQL
dialect, for example). 



1. How do i run Gerwin?

To type:

     $ gerwin

should work if you have tcl/tk installed in your GNU system.



2. Where can i find updates and Gerwin related material?


On the Gerwin homepage, of course: http://es.gnu.org/~jemarch/gerwin

You can also go directly to the GerWin savannah page: http://savannah.nongnu.org/projects/gerwin


3. Where is the documentation?


Hmm... currently there is not documentation, sorry.

Anyway, the tool is fairly simple and (i hope) intuitive. If you
become confused using gerwin, feel free to ask on jemarch@gnu.org


4. How can i enlarge the draw space?


Use the arrow keys to change the canvas size:


             - vertical

                  ^
                  |
                  |
- horizontal  <--- --->   + horizontal
                  |
                  |
                  v
       
             + vertical
