41# Try out affixes to see if they produce valid roots
42#
43# Usage:
44#
45#       tryaffix [-p | -s] [-c] dict-file affix[+addition] ...
46#
47#       The -p and -s flags specify whether prefixes or suffixes
48#       are being tried;  if neither is specified, suffixes are assumed.
49#
50#       If the -c flag is given, statistics on the various affixes are given:
51#       a count of words it potentially applies to, and an estimate of the
52#       number of dictionary bytes the flag would save.  The estimate will
53#       be high if the flag generates words that are currently generated
54#       by other flags.
55#
56#       The dictionary file, dict-file, must already be expanded and sorted,
57#       and things will work best if uppercase has been folded to lower with
58#       'tr'.
59#
60#       The "affixes" are things to be stripped from the dictionary
61#       file to produce trial roots:  for English, "con" and "ing"
62#       are examples.  The "additions" are letters that would have
63#       been stripped off the root before adding the affix.  For
64#       example, the affix "ing" strips "e" for words ending in "e"
65#       (as in "like --> liking") so we might run:
66#
67#           tryaffix ing ing+e
68#
69#       to cover both cases.
