    Eukleides is a computer language devoted to elementary plane
geometry. It aims to be a fairly comprehensive system to create
geometric figures, either static or dynamic. It allows to handle basic
types of data: numbers and strings, as well as geometric types of data:
points, vectors, sets (of points), lines, circles, and conics.

    A Eukleides script usually consists in a declarative part where
objects are defined, and a descriptive part where objects are drawn.
Nonetheless, Eukleides is also a full featured programming language,
providing conditional and iterative structures, user defined functions,
modules, etc. Hence, it can easily be extended. A quick start page and
some code samples are available on-line (www.eukleides.org), in addition
to the Eukleides Reference Manual which is maintained as a Texinfo
manual.

    The Eukleides distribution provides two distinct interpreters:
'eukleides' and 'euktopst,' and three shell scripts: 'euktoeps',
'euktotex', and 'euktopdf'. The former interpreter produces Encapsulated
PostScript (EPS). The later, which is run by the scripts, produces
TeXable PSTricks macros. The 'euktoeps' script is an alternative to
'eukleides' when mathematics typesetting is required. The two other
scripts are useful when using Eukleides together with LaTeX (see section
6.2 in Eukleides Reference Manual).

platform, hence it should build on most of the recent Unices, provided
some common tools are installed. For instance, when using a Debian based
distribution, you may need to install the following packages: flex,
bison, libreadline-dev, texinfo.
