Each line is either a command, +a blank line, or a comment. + +Blank lines are ignored.

They are marked with a B<#> in the first column +(no leading whitespace), and continue to the end of the line. + +Commands consist of any text containing one of the draw instructions +listed below. The instruction must be in upper case, and may be preceded +and/or followed by anything at all (but only one instruction per line +is read). + +=head2 Instructions + +Each instruction moves one pixel, in either plotting or non-plotting +mode.
