Archives generated using the Unix LHA tool, from the Debian package
(version 1.14i-10.3).

The following are files with level 1 header (with the -1 command
line option). Equivalent files also exist for level 0 and 2 headers.

  h1_lh0.lzh     - Archive containing uncompressed (stored) file.
  h1_lh5.lzh     - Archive containing compressed file (-lh5-: -o5 option)
  h1_lh6.lzh     - Archive containing compressed file (-lh6-: -o6 option)
  h1_lh7.lzh     - Archive containing compressed file (-lh7-: -o7 option)
  h1_subdir.lzh  - Archive containing subdirectories.
                   This archive has specially chosen permissions - the file
                   is contained in a directory without write permissions.
                   The archive therefore has to be extracted carefully,
                   with the directory's contents extracted before the
                   permissions on it are set.  The Unix LHA tool, although
                   it was used to create this archive, fails to extract it.
  h1_symlink.lzh - Archive containing a Unix symbolic link.

h0_subdir.lzh is broken - because of the header level, the filenames are
empty.

In addition, there are also these:

  lh6_long.lzh - Large -lh6- compressed file.
  lh7_long.lzh - Large -lh7- compressed file.
