Ladder diagram (LD) is a graphical programming language
that has evolved from electrical wiring diagrams for relay
control systems used with programmable controllers (PLC)
as described in the international standard IEC-61131-3. A
LD program enables the programmable controller to test
and modify data by means of standardized graphic symbols.
These symbols are laid out in networks in a manner similar
to a ``rung'' of a relay ladder logic diagram. This library
provides TikZ symbols to draw high quality ladder diagrams.
All standard and some non-standard symbols are possible,
including all kinds of contacts, coils and blocks. I decided
to write this package, despite of the fact that there is
available another package named `ladder' that also uses TikZ
to typeset ladder diagrams, because that package seems to
lack support for blocks. The tikz-ladder, on the contrary,
supports all features described in IEC-61131-3, namely,
blocks (for functions and function blocks), contacts and coils.
