Ispell is a program that helps you to correct typos in a file, and to
find the correct spelling of words.  When presented with a word that
is not in the dictionary, ispell attempts to find near misses that
might include the word you meant.

The best way to use ispell is with GNU EMACS.  For documentation about
this mode, see the info topic "ispell".

Ispell can also be used by itself, and in this case the most common
usage is "ispell filename".  If ispell finds a word that is not in the
dictionary, it is printed at the top of the screen.  Ispell then
checks the dictionary for near misses - words that differ only by a
single letter, a missing or extra letter, or a pair of transposed
letters.  Any that are found are printed on the following lines, and
finally, two lines of context containing the word are printed at the
bottom of the screen.  If your terminal can type in reverse video, the
word itself is highlighted.

If you think the word is correct as it stands, you can type either
"Space" to accept it this one time, "A" to accept it for the rest of
this file, or "I" to accept it and put it in your private dictionary.
If one of the near misses is the word you want, type the corresponding
number.  Finally, you can type "R" and you will be prompted for a
replacement word.  The string you type will be broken into words, and
each one will also be checked.  You can also type "?" for help.

If ispell is started with no arguments, it enters a loop reading words
from the standard input, and printing messages about them on the
standard output.  You can use this mode to find the spelling of a
problem word.
