The macro ELTEX is for drawing simple electrotechical schemas and their use as pictures in articles, books prepared by LATEX (This is repaired version -some mistakes were repaired) Macro is cca 80 kB large withouth spetial requirements to hardware. Contains only some devices (is is purposeful) and drawing is manual. If you are not spetial circuit designer and you sometimes need simple scheme use in your article writen in LATEX this macro can be useful. Professional design software as ORCAD, ORCADESP, AUTOCAD have great requirements to hardware of PC and use is bounded to licence (hardlock). To join their schemas to your article can be problem. INSTALLATION File ELTEX.STY put to the directory where you have other files *.sty and it is all (here must be also BEZIER.STY but it is standart program of any LATEX implementation). Put one of two files ELTDOC1.TEX or ELTDOC2.TEX to the current directory. This is documentation for use with examples. ELTDOC1.TEX is writen in czech (code LATIN 2), ELTDOC2.TEX is writen in english. This macro has certainly some imperfections. Drawing the schemas has large variability and it is problem to deign in this case flexible universal macro for various requirements with relative simple system of commands.
