# Description:
#     Rules for copying files from the binary file cache.

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.
