+If you are compiling on an MSDOG-like system which has long file
+names, you may need to do `SET LFN=y' for some of the commands,

+djtar truncates file names to 8.3 naming as it extracts files, even if
+the system allows long file names, and this ensures that build
+procedures designed for 8.3 file names still work. Use as in `djtar x
+foo.tar' or `djtar x foo.tgz'.

You can find out if you have a dpmi host by running go32 (part of
djgpp) without arguments; it will tell you if it uses dpmi memory.
