# Description:
# Rules for copying files from the binary file cache.
ifndef SKIP_BINARY_FILES
ifdef BINARY_FILES
# Rules for BINARY_FILES directive.
#
# The BINARY_FILES directives are used to include files out of the binary
# files cache (see 'hb cacheadd' command). This cache exists to keep
# binary files outside of git, because they take a larger space in the git
# database, especially if they change frequently.
#
# The BINARY_FILES variable is a set of <destination>:<hash_value> pairs.
# The destination is where the make system should put the file. The hash
# value tells which version of a file to use and it comes from the
# 'hb cacheadd' tool when a version of the file is added to the binary
# files cache.
