 Requirements

+ULha requires free `lha`_ implementation to work. There is another lha
+implementation under development - `lhasa`_, although it is currently limited
+to list and extract only.
+
+Limitations
+-----------
+
+For filenames which contain other characters outside of ASCII set, there is no
+way to operate on them as `lha`_ simply ignore those files. Extracting full
+archive will extract also those files, although names would be incorrectly
+decoded, and hence, unusable on the AmigaOS. Looking forward for the `lhasa`_
+to be completed, and then will switch to it.
 
 Installation
