1) PURPOSE

The language Eukleides is an Euclidean geometry drawing language. It has been
designed in order to be as close as possible from what human beings would say to
describe elementary Euclidean geometry figures. In many cases, it makes possible
to completely avoid the use of Cartesian coordinates.

  The X-Window program `xeukleides' is a complete system for editing and viewing
figures described in this language.The figures can be interactive, i.e., while
viewing, it is possible to modify some numerical values using the keyboard.
  
  If you want to insert some geometry figures in a (La)TeX document or convert a
figure in some vector graphic format (like EPS), you should also get the
`eukleides' distribution.

This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later
version.

  See file COPYING for more details.

3) INSTALL

The software `xeukleides' has been developed on a GNU/Linux system. It should
build on any Unix system where `flex', `bison' and `GTK+' have been ported.
Furthermore, you'll need `makeinfo' to format the documentation file, and/or
TeXinfo to get a hardcopy.

  As usual, type "make install". Default installation directories are
`/usr/local/bin', `/usr/man' and `/usr/info'.  You'll have to edit the Makefile
to change this.

  To get a printable documentation file, type "make book". Default paper format
is A4. If you want to use letter paper instead, you'll have to edit the Makefile
to set the PAPER macro empty.

4) DOCUMENTATION

Once installed see man page for usage and info page for language description.
The directory `samples/' contains a set of selected Eukleides source code files.
These files are intended to demonstrate the interactive abilities of
`xeukleides'.

5) NOTE

The `eukleides' and `xeukleides' softwares were formerly named `euklides' and
`xeuklides'. It had to be changed because there is already another program named
`euklides'.
