Small CLI utility for calculating all possibilities given T9 input.
Does not account for multiple presses... 66 -> [MNO6][MNO6] not N.
Not particularly fast when checking wordlist.
C99 compliant.
OPTIONS:
-i List entries with their index
-d Verify results in wordlist </usr/share/dict/words>
-df Same as -d but match full word
-w <path> Enable dictionary verification with custom wordlist
-e <n> Select the n'th entry in the return list
-h Prints help information
$ t9 -i -df 4355
1: gell
2: hell
