EUKLEIDES version 1.0.0 Copyright (c) Christian Obrecht 2000-2004 1. PURPOSE The language Eukleides is a Euclidean geometry drawing language. It has been designed in order to be close to the traditional language of Euclidean geometry. In many cases, it makes possible to completely avoid the use of Cartesian coordinates. There are three situations where Eukleides can be useful: * You want to insert some geometric figures in a (La)TeX document. In this case you can insert some Eukleides commands within your TeX source file and run `eukleides' in filter mode on the source file to obtain a ready-to-TeX file. * You want to create a geometric figure in vector graphic format. In this case you can run the shell scripts `euk2eps' (for EPS format) or `euk2edit' (for other formats like the ones used in Xfig or Sketch) on a Eukleides source file. * You want to create an interactive geometric figure. In this case you can use the X-Window program `xeukleides'. This software is distributed separately. 2.

See file COPYING for more details. 3. INSTALL The software `eukleides' has been developed on a GNU/Linux system. It should build on any system where `flex' and `bison' have been ported. Furthermore, you'll need `makeinfo' to format the documentation file, and/or Texinfo to get a hardcopy. To obtain printable files after running `eukleides', the PSTricks package is mandatory. Last, to run the shell script `euk2edit' you'll also need to have `pstoedit'. As usual, type `make install'. Default installation directories are `/usr/local/bin', `/usr/local/man' and `/usr/local/info'. You'll have to edit the PREFIX macro in 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 files. Some of these files were written to illustrate geometry exercises, others illustrate some classical geometry theorems. 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'. 6.
