| bloat | rnd_cfn_coord | 0 | core: size of box-style clearance around text objects; old plugins: gap between copper features on different nets | 
| shrink | rnd_cfn_coord | 0 | [OBSOLETE] minimum overlap between connected copper features | 
| min_wid | rnd_cfn_coord | 0 | core: minimum copper thickness in stroked text, core+plugins: implicit outline rectangle thickness | 
| min_slk | rnd_cfn_coord | 0 | core: minimum silk thickness in stroked text, core+plugins: implicit outline rectangle thickness on silk layers | 
| min_drill | rnd_cfn_coord | 0 | [OBSOLETE] minimum drill diameter | 
| min_ring | rnd_cfn_coord | 0 | [OBSOLETE] minimum annular ring | 
| poly_isle_area | rnd_cfn_real | 0 | polygon island mininum area used to throw out islands too small in MorphPolygon; specified in nm^2; note: due to historical bugs, half or double of the value may be used by the code. | 
| fab_author | rnd_cfn_string | 0 | Full name of author for FAB drawings | 
| initial_layer_stack | rnd_cfn_string | 0 | deprecated. | 
| paste_adjust | rnd_cfn_coord | 0 | Adjust paste thickness | 
| hierarchy_sep | rnd_cfn_string | 0 | separator character in hierarchic design levels (only the first character is used); e.g. if it is /, S1/S2/R4-5 is interpreted as S1/S2/R4 as the refdes (5 is terminal id), and that R4 is under S2 which is under S1 in the hierarchy |
