     MKSACFS(8)                                             MKSACFS(8)

     NAME
          mksacfs - make a compressed file system

     SYNOPSIS
          disk/mksacfs [-u] [-b blocksize] [-o file] source

     DESCRIPTION
          Mksacfs copies files from the file tree source (default .)
          to a the sacfs(4) file system archive file.

          The files and directory structure are divided into blocksize
          (default 4096) byte blocks.  Larger blocks make large files
          more compact but take longer to access.  Blocksize must be
          at least 116.  If -u is given, the blocks are not
          compressed.  Otherwise each block is compressed using an
          efficient compression algorithm.
