The link to the directory of decoding problems can not be used from git so
I have removed it and linked to www.webpidgin.co.uk/4Sue where all this
lives online

I decided to remove all the double letters that were being coded twice
where only a single sound was present.

i tidied this with the
                    remove-dbl-letters.sed sed script

I then noticed the word bookkeeper was an exception to this rule
so I greped the cmu7.0a dictionary for cases of genunine
double letters to produce the

true-doubles.txt file

this was mercifully short so i then hand reinstated the true doubles
in the

file input-doubles-collapsed-true-doubles-reinstated
Not sure what i'm doing
