DESCRIPTION
     archive_read_support_filter_bzip2(),
	     archive_read_support_filter_compress(),
	     archive_read_support_filter_grzip(),
	     archive_read_support_filter_gzip(),
	     archive_read_support_filter_lrzip(),
	     archive_read_support_filter_lz4(),
	     archive_read_support_filter_lzma(),
	     archive_read_support_filter_lzop(),
	     archive_read_support_filter_none(),
	     archive_read_support_filter_rpm(),
	     archive_read_support_filter_uu(),
	     archive_read_support_filter_xz(),
	     archive_read_support_filter_zstd(),
	     Enables auto-detection code and decompression support for the
	     specified compression.  These functions may fall back on external
	     programs if an appropriate	library	was not	available at build
	     time.  Decompression using	an external program is usually slower
	     than decompression	through	built-in libraries.  Note that "none"
	     is	always enabled by default.
     archive_read_support_filter_all()
	     Enables all available decompression filters.
     archive_read_support_filter_program()
	     Data is fed through the specified external	program	before being
	     dearchived.  Note that this disables automatic detection of the
	     compression format, so it makes no	sense to specify this in con-
	     junction with any other decompression option.
     archive_read_support_filter_program_signature()
	     This feeds	data through the specified external program but	only
	     if	the initial bytes of the data match the	specified signature
	     value.

RETURN VALUES
     These functions return ARCHIVE_OK if the compression is fully supported,
     ARCHIVE_WARN if the compression is	supported only through an external
     program.

     archive_read_support_filter_none()	always succeeds.

ERRORS
     Detailed error codes and textual descriptions are available from the
     archive_errno() and archive_error_string()	functions.
