script to mark mispelled words in a text file

[Glen W. Plantz]

I need a script to "mark" misspelled words in a text file. I am
aware of the the unix "spell" command, but was interested if anyone
has a script (cshell, awk, perl, etc) to input as a parameter, a file
indicating a "local dictionary" of words to skip, and the text file
to check, outputting this same text file with the misspelled words marked
somehow.
	Thanks in advance,
