+# This file is part of Spack and sets up the spack environment for
+# bash shells. This includes dotkit support as well as putting spack
+# in your path. Source it like this:
+#
+# . /path/to/spack/share/spack/setup-env.bash
+#
+#
+
+
+########################################################################
+# 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.
