The added characters at the end of each line form a sequence check used
by the Dumas UUD program.  They are ignored by uudecode, but if your
version gets confused, you can simply remove the last character of each
line (sed -e 's/[a-z]$//') before decoding.  The table is also used by
UUD, but should be ignored by standard uudecode.

I have not had problems decoding all kinds of uuencoded files with UUD,
including all of those from the MS-DOS group.  I send out UUE-encoded
files all the time and haven't heard of any problems.

I've made some changes to UUD which let me decode whole bunches of files
at one shot -- very handy.  Dumas has saved me a lot of trouble!
