# This is a template package file for Spack.  We've put "FIXME"

# them, you can save this file and test your package like this:
#
#     spack install glibc
#
# You can edit this file again by typing:
#
#     spack edit glibc
#
# See the Spack documentation for more information on packaging.
# If you submit this package back to Spack as a pull request,
# please first remove this boilerplate and all FIXME comments.
