ABlogix.m4: The Autologix macro can draw inputs on the left but the added drawing complexity may require hand tuning with second-argument options: L puts the inputs on the left, R reverses their order, V scans the input arguments in reverse order, and offset=value displaces the array of inputs

Geometry.m4: Some geometrical constructions

Smithchart.m4: A Smith chart

ex09.m4: Illustrating the macro dimension_(linespec, offset, label, D|H|W|blank width, tic offset,<-|->). A negative second argument implies an offset to the right of the linespec direction. A label starting with " or sprintf is copied literally. If label is an s_box(...) then setting argument 4 to H, W, or D tailors the blank width to the s_box height, width, or diagonal respectively; i.e., W is equivalent to s_wd+textoffset*2. The macro arcdimension_ is similar but the first argument specifies the arc to be dimensioned and the second argument is the outward radial offset of the dimension arrow arc.

The right object adjusts the size of dots to produce a halftone effect
