Note: stored reference files are of format boardname.ref or boardname.ref.gz if they are compressed. svg-sort reads a pcb-rnd generated svg on stdin, prints sorted svg: objects within each group sorted alphabetically svg-diff s1 s2 sort pcb-rnd generated svgs s1 and s2 and print diff s1 s2; result written to stdout in diff -u format diff b1 b2 run pcb-rnd to generate svgs of b1 and b2 and print their diff; result written to stdout in diff -u format. Boards can be of any format pcb-rnd can load. svg-vis-comp s1 s2 generate a visual comparison of s1 and s2, diffs highlighted: - lines of the diff with blue, + lines with red in a new group, over the faded version of s1. vis-comp b1 b2 generate a svg visual comparison of board files b1 and b2, diffs highlighted: - lines of the diff with blue, + lines with red in a new group, over the faded svg render of b1. Boards can be of any format pcb-rnd can load. test brd run pcb-rnd on brd and compare the resulting svg to a saved sorted svg reference file called brd.ref test-all dir1 [dir2 dirN...] run test on all boards with a ref available under all directories listed, recursively. gen-ref brd1 [brd2 brdN...] generate the initial svg reference file for all board files named
