-"""
-Use extended attributes instead of database files
-
-1. Input files will be made writable
-2. This is only for systems providing extended filesystem attributes
-3. By default, hashes are calculated only if timestamp/size change (HASH_CACHE below)
-4. The module enables "deep_inputs" on all tasks by propagating task signatures
-5. This module also skips task signature comparisons for task code changes due to point 4.
-6. This module is for Python3/Linux only, but it could be extended to Python2/other systems
-   using the xattr library
-7. For projects in which tasks always declare output files, it should be possible to
-   store the rest of build context attributes on output files (imp_sigs, raw_deps and node_deps)
-   but this is not done here
-
-On a simple C++ project benchmark, the variations before and after adding waf_xattr.py were observed:
-total build time: 20s -> 22s
-no-op build time: 2.4s -> 1.8s
-pickle file size: 2.9MB -> 2.6MB
