Checking spelling

The spell command filters through a file looking for things that look like words, and spits out those which don't appear in the computers dictionary file. Examples:

• spell myfile   displays all the possible misspellings from the file `myfile'
• spell myfile > errors   writes all the possible misspellings from the file `myfile' to a file named `errors'

The look command displays all the words in the computer's built-in dictionary which begin with the given letters. Examples:

• look aque   prints out `aqueduct' and `aqueous'
• look persi   prints out `Persia', `Persian', `persiflage', `persimmon', `persist', `persistent'
