+# This file is part of Spack and sets up the spack environment for zsh shells.
+# This includes dotkit and module support as well as putting spack

+#

+#

+########################################################################
+# 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.
