This is an exprimental program to see if there is any use of this kind
of program. This release is an alpha release (so bugs are expected and stuff
not completed). But the main stuff should work, and there might be fatal
bugs hiding.

Lhx - 0.83.0a

Lhx is a file compression utility that compresses files to an AmigaOS compatible
XZ/LZMA compressed archive. where all AmigaOS file system protection bits and
possible comments are preserved.

XZ/LZMA is the same compression method used as in the acclaimed 7-Zip.

A Quick Comparison Test
A test drawer with some text and exe files, size 4 273 588 bytes:
 - Unpacked:           4 273 588 B  test
 - Lha (-lh5-)         2 929 454 B  test.lha
 - Lha (-lh6-)         2 929 454 B  test2.lha
 - Lhx (XZ/LZMA+lh0)   2 375 368 B  test.lhx

Run the Install file in the package, or:
  1. Copy the "Lhx" file into your "C:" drawer.
  2. Optionally copy the documentation files; "Lhx.manual.doc.txt",
     "Lhx.readme" and "Lhx.readme.info" to presumably "SYS:Documentation".
  3. Done.


; Pack/compress a file
1> lhx NEW somefile.lhx somefile
; Or shorthand works too
1> lhx -n somefile.lhx somefile

; Pack/compress a file from, and to RAM Disk:
1> lhx NEW ram:packed.lhx ram:t/usb.log

; Pack/compress a drawer and a file to RAM Disk:
1> lhx NEW ram:MyGame.lhx MyGame MyGame.info

; For extracting/unpacking the files use the EXTRACT command.
1> lhx EXTRACT packed.lhx
; Or shorthand works too
1> lhx -e packed.lhx

; For extracting/unpacking to the RAM Disk:
1> lhx EXTRACT packed.lhx ram:

0.83.0 alpha: (2018 Feb)
 - Implemented so only correct type of files can be extracted, through checks
   of file-headers (Magic Headers), and not solely of file extensions.
 - Fixed a few other issues regarding filetypes/fileheaders.
 - When extracting, the destination dir is checked that it really is a
   directory and not a regular file.
 - Fixed its own directory for documentation in AutoInstall.
 - Clarified and fixed typos in help/documentation.
 - Among other things.
0.82.0 alpha: (2018 Feb)
 - Fixed a number of bugs.
 - Checks that the files to be archived / extracted to actually exists.
 - A lot of internal refactoring.
 - Implemented a logger (RAM:T/Lhx.log), to help finding bugs (although not all
   operations are logged (yet)).
 - Other miscellaneous fixes and improvements.
0.81.0 alpha: (2018 Feb)
 - Fixed bugs/issues with files not found and old temp. files.
 - Corrected wrong months in Recent section, thanks MickJT.

 - Clarified readme and help text.
0.80.0 alpha: (2018 Feb)  - 7z superseded by XZ/LZMA and program renamed to Lhz
(from L7z), thanks for    suggestion Fredrik Wikström. XZ/LZMA is a subset of 7z
(used in 7-Zip).
 - Miscellaneous fixes and improvements.
0.7.0 alpha: (2018 Jan)
