To tidy and sort a JP Software 4NT/4DOS hidden descript.ion file.
These files are used by the 4NT DESCRIBE utility to track what
your various files or for. See http://mindprod.com/jgloss/fornt.html
for more information on the 4NT command processor.

First make the directory containing the usually-hidden descript.ion file
current. e.g.

C:
cd \env

Then invoke the java program with:

java.exe -jar C:\com\mindprod\fourtidy\fourtidy.jar

If you have Excelsior Jet,
(http://mindprod.com/jgloss/jet.html/) you can compile the
jar and simplify that long-winded command to:

fourtidy.exe

To save typing, create a *.BAT file on the path containing the command.
You might also want to hide/reveal the descript.ion file with:
attrib +h descript.ion
attrib -h descript.ion

Fourtidy will sort, tidy, and prune duplicates in the
descript.ion file. It will also create a non-hidden file
called readme.txt with the information about all your files
in the directory in aligned human readable form.

Be careful, fourtidy will replace any existing readme.txt file you
may have in the directory!!
