########################################################################
# This is a wrapper around the spack command that forwards calls to
# 'spack use' and 'spack unuse' to shell functions. This in turn
# allows them to be used to invoke dotkit functions.
#
# 'spack use' is smarter than just 'use' because it converts its
# arguments into a unique spack spec that is then passed to dotkit
# commands. This allows the user to use packages without knowing all
# their installation details.
#
# e.g., rather than requring a full spec for libelf, the user can type:
#
# spack use libelf
#
# This will first find the available libelf dotkits and use a
# matching one. If there are two versions of libelf, the user would
# need to be more specific, e.g.:
#
# spack use libelf@0.8.13
#
# This is very similar to how regular spack commands work and it
# avoids the need to come up with a user-friendly naming scheme for
# spack dotfiles.
