Import dmsdos-0.9.2.3pre2 -- this is the userland part of some code

which can access files on DBLSPACE compressed MSDOS volumes.
Not maintained, but it just helped me to salvage files from an old
harddisk, so I thought it is worth keeping.
(It can be integrated into the "mc" norton-commander clone - you'll
find out details in its documentation.)
