  The format of the PATH environment variable with colon separated values allows you easy to add a new path at the front or end.
  But all other operations(swap, remove) require the help of an editor and some manual moves.
  pato is an approach to solve this problem.
  
  All commands that manipulate a PATH variable write the new PATH variable as result to the output stream.
  
  == OPTIONS
  
  -e::
  Read the PATH variable from the current environment. This is also the default option.
  
  -i::
  Read the PATH variable from the standart input.
  
  == COMMANDS
