# Declare an alias release-config

#

# This should be used to declare a release as an alias of another, meaning no

# release config files should be present.

#

# $1 config name

# $2 release config for which it is an alias

# Declare or extend a release-config.

#

# The order of processing is:

# 1. Recursively apply any overridden release configs.  Only apply each config

#    the first time we reach it.

# 2. Apply any files for this release config, in the order they were added to

#    the declaration.

#

# Example:

#   With these declarations:

#     $(declare-release-config foo, foo.scl)

#     $(declare-release-config bar, bar.scl, foo)

#     $(declare-release-config baz, baz.scl, bar)

#     $(declare-release-config bif, bif.scl, foo baz)

#     $(declare-release-config bop, bop.scl, bar baz)

#

#   TARGET_RELEASE:

#     - bar will use: foo.scl bar.scl

#     - baz will use: foo.scl bar.scl baz.scl

#     - bif will use: foo.scl bar.scl baz.scl bif.scl

#     - bop will use: foo.scl bar.scl baz.scl bop.scl

#

# $1 config name

# $2 release config files

# $3 overridden release config.  Only applied for $(TARGET_RELEASE), not in depth.

# $3 overridden release config
