name | man dat ory | description | value (bold: default)
--- | --- | --- | ---
ny | yes | number of pins (in vertical direction) |
nx |  | number of columns (in horizontal direction; e.g. single row connectors have 1, headers have 2) |
eshift |  | double pin spacing, shift even rows or columns by 1 spacing (optional; default: don't shift) |

none | do not shift anything |
etrunc |  | truncate the last pin of a shifted row or column | Boolean: yes/no, true/false, 1/0 ; Default: false
true: |  | false: |
sequence |  | pin numbering sequence |
normal | increase by y first, then by x |
pivot | increase by x first, then by y |
zigzag | "dip-style" numbering in zig-zag: number odd x rows by y ascending, even x rows by y descending |
