"""MetaData file remapper

Takes a MetaData file and maps all StuntDoubles back to the periodic box.
Will optionally replicate the system in the three box directions, or 
translate every object in the box and before writing out a new MetaData file.

Usage: md2md

Options:
  -h,  --help             show this help
  -m,  --meta-data=...    use specified meta-data (.md, .eor) file
  -o,  --output-file=...  use specified output file
  -x,  --repeatX=...      make the system repeat in the x direction
  -y,  --repeatY=...      make the system repeat in the y direction
  -z,  --repeatZ=...      make the system repeat in the z direction
  -t,  --translateX=...   translate all x coordinates by some amount 
  -u,  --translateY=...   translate all y coordinates by some amount
  -v,  --translateZ=...   translate all z coordinates by some amount

Example:
  md2md -m lipidSystem.md -o bigLipidSystem.md -x 2 -y 2 -z 1 -v 35.0
