The order in which the processing happes is important.

1. spelling corrections for common spelling errors
2. idiom conversions
3. junk word removal from sentence
5. special sentence effects (question, exclamation, revert question)
6. abbreviation expansion and canonization
for abbreviations, do not use _ before the .
for apostrophied left side, must follow tokenizing conventions
for apostrophied right side, it means do not spell check the word, the apostrophe will disappear
Format is left phrase separated by _ yields right phrase separated by +
if right side is %value means set that bit on the sentence (%EXCLAMATIONMARK %QUESTIONMARK)
if right side is a ~word its an interjection
only proper names should have capital letters
Right phrase missing means delete left phrase
Substitutions files include:
we use + because we dont want the resulting phrase recognized by the idiom processor and thus cause the processor to delete the phrase
xxx> means sentence then end stop
if you want to have the result NOT tokenized, put it in quotes
