It will read a document from standard input and print on standard output a list of all the misspelled words in the document. If any command line arguments are given, 'spel' should read those files instead of the standard input. The output words should be in lexicographic order, and no word should appear more than once in the output. 'spel' will be given one or more dictionaries of words that are already spelled correctly. It will always try to read the file '/usr/dict/words'. It will also try to read '.spel' files from certain directories. If the user has set an environment variable SPELWORDS, 'spel' should interpret its value as a :-separated list of directories to be searched for '.spel' files. If no SPELWORDS variable is set, 'spel' should search in the user's home directory and in the current directory. If you need a sample dictionary, you can obtain one from http://perl.plover.com/qotw/words/ * * * P.S.: I'm sorry that this week's quiz (and last week's reports) are late. I was detained all through Tuesday and Wednesday by other business. I hope to send out last week's reports tonight. P.P.S: Yesterday was Perl's 15th birthday. Happy birthday, Perl!
