Announcement text: ----------------------------------------------------------------------

From the README:

... This is a set of macros for drawing high-quality line diagrams to include in TeX, LaTeX, or similar documents. The macros were originally intended for electric circuit diagrams containing fundamental elements, amplifiers, transistors, and basic logic gates, but several tools and examples of other types of diagrams are also included. Elements can be scaled or drawn in any orientation, and are easy to modify. The advantages and disadvantages of such a system are similar to those of TeX itself, which is macro-based and non-wysiwyg, with ordinary character input.

The macros are to be processed by m4, and evaluate to drawing commands in the pic little language, which is easy to read and learn. Pic is well suited to line drawings requiring parametric or conditional components, fine tuning, significant geometric calculations or repetition, or to drawings that are naturally block structured or tree structured. Arbitrary formatted text can be included. Free TeX- and LaTeX-compatible interpreters for m4 and pic are readily available.

... EXAMPLES: Read the manual man.ps and view or print the file examples.ps in the examples directory, or for the possibly unstable development version, try http://ece.uwaterloo.ca/~aplevich/Circuit_macros/

A collection of examples and hints intended for his colleagues has been produced by Alan Robert Clark at http://ytdp.ee.wits.ac.za/cct.html ... CHANGES: Version 5.6: Better MetaPost, pdflatex, and xfig support. PDF examples. Reworked diode for easier customization and more options. Improved shade, sfgline, dline, darrow, gap, point_, Point_, opamp, bi_trans, variable, em_arrows, larrow, rarrow, FlipFlop6. New speaker, bell, microphone, buzzer. Negated logic gate inputs and IEEE box logic gates. ----------------------------------------------------------------------

Thanks for the upload. I installed this as suggested replacing the previous version in CTAN:graphics/circuit_macros/
