# An overlay has a type defining the way modules in this overlay
# make modules in the other overlays unavailable.
#
# 'normal'
# Make modules in other overlay unavailable with the same full name.
# If the overlay doesn't support groups, the overlay should provide
# only modules with different names from the modules in the other
# overlays. Otherwise you modules as available which cannot be loaded.
# Example:
# A overlay providing modules with name gcc doesn't conceal the gcc
# modules in the base overlay, but they are listed as available.
#
#
# 'hiding'
# Make modules in other overlay unavailable with the same name.
# Examples:
# - If a module with name 'gcc' is in a overlay with this
# type, only the gcc modules in this overlay are available. This
# can for example be used to conceal old versions of gcc.
# - In same case we need special variants of a module for a system,
# for exampe openmpi and mpich. Variants of these software can be
# made available in an overlay. If such an overlay is used, modules
# which should not be used can be concealed.
# If the overlay doesn't support groups, a module in the overlay
# conceals all modules in other overlays independend from the group.
# Example:
# - In the Spack overlays - which doesn't support groups - are modules
# with name gcc. The gcc modules in the Spack overlays conceals the
# gcc modules in the group Programming of the base overlay.
# 'replacing'
# This type can be used to make hole groups unavailable.
