module Roll

  # This script builds a list of all roll-ready bin locations
  # and writes that list as an environment setting shell script.
  # On Linux a call to this to you .bashrc file. Eg.
  #
  #   if [ -f ~/.rollrc ]; then
  #       . roll
  #   fi

  # Currently this only supports bash.

  # TODO: It would be better to "install" executables
  # to an appropriate bin dir, using links (soft if possible).
  # There could go in ~/.bin or .config/roll/<ledger>.bin/
