primarily intended so that parts' internal segment and feature names
can be remapped to correspond to the layout naming scheme.

- N N' remaps an entire segment including all features

The effect is that (sub)segments or features used in segment
commands are translated when the segment command is read; the

Command-line options
-D turn on debug (level 1) } currently only debug levels are
in each direction. xp is multiplied by 270mm; yp
is multiplied by 190mm.

Turn on and off drawing of elements in groups.
These are abbreviations for various -E... options.

<layersel> (for -e and -E) works as follows:
When file says `layer KL', default drawing element set is set
%L bbox no locs, no bbox
there were no locs, so there is no bounding box
usu because input file was just obj defns and showlibrary
+ %L segmentpart I KL [-]S D X0 Y0 A0 X1 Y1 A1
+ records that a piece of subsegment S is drawn in the subsegment
+ encoding. The piece is of length D, in layer KL (which may be
+ the empty string, depending on layer configurations), and runs
+ from the loc X0,Y0,A0 to X1,Y1,A1. I is a counter which starts
+ at 0 and is simply there to help cross-reference between
+ various programs and formats.
Scope S is
