asc-plot3 — produce Plot3 instructions from ASCII representation
Reads a stream of ASCII data representing Plot3 instructions and converts it to plot3(5) format. asc-plot3 reads from standard input and writes to standard output if file names are not supplied.
The input should consist of lines of the form
c arg arg ...
where c is one of the single-character Plot3 command names, and it is followed by white-space-separated arguments of appropriate number and types for that command. Optional white space and lines beginning with the comment character `#' are ignored.
