Here is a newer version of my visual spelling checker.  Added an ifdef for SYSV
compatibility (don't define BSD in the Makefile).  Also fixed a bug:  When you
(used to) exit a document without looking at all the words, null strings were
passes to ex.  Could have wierd effects.  I also re-organized the code based on
my current programming techniques.

XX** SP **
XX
XXSp is a visual spelling program that is based upon existing UN*X utilites.
XXIt may be run on one or more files, and for each file, it presents a
XXword-by-word list of the words received from spell(1).  You may then take
XXany of a host of actions.
XX
XXThis program has come through many stages during its development.  When it was
XXoriginally written, it was designed around a shell script posted in net.sources
XXin 1985 that put all misspelled words into a file, had you correct the file,
XXand then, from the difference between the files, made the corrections.
XX
XXThe current version is so different from the original shell script that I don't
XXcredit the original authors any more.  After completing this program, I have
XXnoticed a resemblance to both `ispell' and `correct'.  However, this was written
XXbefore I ever saw either of those programs, and no code was taken from either
XXone when writing this.
XX
XXTo install:
XX
XX    1) Edit `sp.h' to reflect your current situation (mainly locations
XX    of system programs).
XX
XX    2) Edit Makefile and change `BIN', `MAN', `CC', and `CFLAGS' to
XX    their proper values.
XX
XX    3) Type `make'.
XX
XX    4) If everything test out ok, type `make install'.

XX.SH NAME
XXsp \- check spelling of a document and fix any mistakes
XX.SH SYNOPSIS
XX.B sp
XX[
XX.B \-d
XX.B dictionary
XX]
XX.B file
XX[
XX.B file2
XX.B ...
XX]
XX.SH DESCRIPTION
XX.IR sp
XXcalls spell(1) to check the spelling of a document.  If you specify a
XXpersonal dictionary (with the \-d option), this is searched in addition
XXto the system dictionary for proper spellings of words.  If you do not
XXspecify a personal dictionary,
XX.IR sp
XXchecks for an environment variable called DICT.  If it exists, it is taken
XXto be the full path to your personal dictionary.  If you do not
XXspecify a personal dictionary or have $DICT defined, the file ``spelldict''
XXin your current directory will be established as your personal dictionary.
XX.PP
XXOnce the mis-spelled words are identified, you are prompted word by
XXword for an action to take.  Your choices are given in brackets and
XXexplained below.
XX.IP A
XXMark the word for addition to your personal dictionary.
XX.IP C
XXMark the word for correction.  You will be asked for the correct spelling.
XX.IP I
XXIgnore the word in question.  This is the default option and is
XXgenerally used when a word is spelled correctly for its usage, but
XXyou don't want it added to your personal dictionary.
XX.IP L
XXLook up a string in the system dictionary.  This is appropriate for
XXobtaining the proper spelling of the word.  You will be prompted for a string
XXthat look(1) will use on the system dictionary.
XX.IP W
XXShow where the word occurs in the document.  Runs grep(1) on the document
XXfile searching for occurrences of the word and prints out lines that
XXcontain the word.
XX.IP ^
XXGo to previous document (given on command line).  If your current document
XXis the first given on the command line, this will re-run spell(1) on your
XXcurrent document.  If you have marked any words for correction or
XXaddition to your personal dictionary, you will be
XXasked whether or not you want to save your changes.
XX.IP #
XXGo to next document (given on command line).  If your current document is
XXthe last given on the command line, this exits the program.  If you
XXhave marked any words for correction or addition to your personal
XXdictionary, you will be asked whether or not you want to save your changes.
XX.IP +
XXGo to next word.  If you haven't taken action with the current word, this
XXoption is equivalent to an ignore (don't correct or add to personal
XXdictionary).  Otherwise, previous actions hold true, i.e. if you correct
XXa word, hit a '-' to go back to it, and hit a '+' to skip forward past it,
XXthe correction would still be the course taken.  However, if you hit an
XX'I' to skip forward past it, no correction would take place.
XX.IP -
XXGo to previous word.  This is the course of action to take if you
XXmess up a correction or change your mind in some way.
XX.IP ?
XXThis will display a short help menu.
XX.IP ^L
XXThis will redraw the screen (as in vi(1)).
XX.PP
XXAfter you have processed all the words, you are prompted for an
XXadditional action.  You may go to either the previous or the next document.
XXIn either case, you will be asked whether or not you wish to save your changes.
XXIn this manner, you can make corrections to a file, and then back up to check
XXyour corrections.  Corrections are made to the documents via
XX.B ex(1).
XX.PP
XXThe spelling checking is done one file at a time, so if you have the same
XXmis-spelled word in several files, you will have to correct it for each file.
XXHowever, the personal dictionary is updated between the checks on each file,
XXso additions to it will be available when the next file is checked.
