MULTIPLE FILE TEST

The files in "lha_e138.run" (the distribution archive of LhA 1.38e) were
extracted and recompressed with various archivers.

Also tested were compressing the complete INCLUDE directory of SAS/C
6.51 (C and ASM header files), and compressing the C directory of SAS/C
6.51 (containing all the compiler's command-line tools).

The appropriate commands were used for each archiver in order for it
to preserve path names and recurse into subdirectories.  For LZX, the
"-M5000" option was also used to allow large merged file groups.

These results demonstrate that not only is LZX by far the most compressive
utility for the Amiga, but that it is, astoundingly, also one of the
fastest!

NOTE: Zip's "-r" option was unable to recurse into all directories and
      collect only "*.h" files, so Zip has been excluded from this test.
