+Midnight Commander ulzx
+=======================
 
-Those are Midnight Commander extfs plugins for handling several archive types
-mostly known from AmigaOS - like **lha**, **lzx** and disk images like **adf**
-and **dms**.
+Midnight Commander extfs plugin for handling lzx Amiga archives.
 
-Installation
-============
-
-See individual installation plugins below. Basically it comes down to:
-
-* copying ``extfslib.py`` and plugin files to ``~/.local/share/mc/extfs.d/``
-* installing binary handlers (lha, unlzx, xdms and unadf)
-* adding an entry in ``~/.config/mc/mc.ext``::
-
-    # arch
-    regex/\.pattern$
-         Open=%cd %p/handler_filename://
-
-ULha
-====
-
-ULha is an extfs plugin which can be used with lha/lzh/lharc archives.
-Personally, I've use it almost exclusively for archives created long time ago
-on my Amiga. Both reading from and writing into archive was implemented.
-
-Requirements
-------------
-
-ULha requires `free lha <http://lha.sourceforge.jp>`_ implementation to work.
-
-Installation
-------------
-
-* copy ``extfslib.py`` and ``ulha`` to ``~/.local/share/mc/extfs.d/``
-* add or change entry for files handle in ``~/.config/mc/mc.ext``::

-UAdf
-====
-
-UAdf is an extfs plugin suitable for reading .adf, .adz and .dms Amiga floppy
-disk images. Due to limitations of the
-`unadf <http://freecode.com/projects/unadf>`_, file access inside disk image is
-read only.
-
-In case of corrupted or no-dos images, message will be shown.
-
-Requirements
-------------
-
-It requires ``unadf`` utility from `ADFlib <https://github.com/lclevy/ADFlib>`_
-repository, with included `that commit
-<https://github.com/lclevy/ADFlib/commit/d36dc2f395f3e8fcee81f66bc86994e166b6140f>`_
-in particular, which introduced separation between filename and comment
-attribute on Amiga Fast File System.
-
-If it turns out that your distribution doesn't provide proper version of ADFlib,
-there will be a need for building it by hand.
-
-It may be done by using following steps:
-
-#. Grab the `sources
-   <http://http.debian.net/debian/pool/main/u/unadf/unadf_0.7.11a.orig.tar.gz>`_
-   and `patches
-   <http://http.debian.net/debian/pool/main/u/unadf/unadf_0.7.11a-3.debian.tar.gz>`_
-   from `Debian repository <http://packages.debian.org/sid/unadf>`_.
-#. Extract ``unadf_0.7.11a-3.debian.tar.gz`` and ``unadf_0.7.11a.orig.tar.gz``
-   into some temporary directory::
-
-   $ mkdir temp
-   $ cd temp
-   $ tar zxf ~/Downloads/unadf_0.7.11a-3.debian.tar.gz
-   $ tar zxf ~/Downloads/unadf_0.7.11a.orig.tar.gz
-   $ cd unadf-0.7.11a
-
-#. Apply Debian patches::
-
-    $ for i in `cat ../debian/patches/series`; do
-    > patch -Np1 < "../debian/patches/${i}"
-    > done
-
-#. Apply the patch from extras directory::
-
-   $ patch -Np1 < [path_to_this_repo]/extras/unadf_separate_comment.patch
-   $ make
-   $ cp Demo/unadf [destination_path]
-
-#. Place ``unadf`` binary under directory reachable by ``$PATH``.
-
-For optional dms support, `xdms <http://zakalwe.fi/~shd/foss/xdms/>`_ utility is
-needed.
-
-Installation
-------------
-
-* copy ``extfslib.py`` and ``uadf`` to ``~/.local/share/mc/extfs.d/``
-* add or change entry for files handle in ``~/.config/mc/mc.ext``::
-
-    # adf
-    type/^Amiga\ .* disk
-        Open=%cd %p/uadf://
-        View=%view{ascii} unadf -lr %f

-UADF Virtual filesystem
-
-This extfs provides quick and dirty read-only access to disk image files for
-the Commodore Amiga adf or adz (gzipped adfs) and dms.
-
-It requires the unadf utility, unfortunately there is no original sources,
-since authors page doesn't exists anymore. Luckily, there is a copy of the
-source (and useful patches) in Debian repository:
-http://packages.debian.org/sid/unadf
-
-There should be one change made to the source of unadf, though. While using
-"-lr" switch it by default also displays comments, separated by the comma.
-However there is no way to distinguish where filename ends and comment starts,
-if comment or filename already contains any comma.
-
-The patched sources are available from: https://github.com/lclevy/ADFlib
-
-It also requires xdms utility, for optional dms support.
-
-Changelog:
-    1.3 Switch to Python3
-    1.2 Added failsafe for filenames in archive with spaces and nodos message.
-    1.1 Moved common code into extfslib library
-    1.0 Initial release
