The replacement pairs improve the quality of the spellchecker. When a word
is misspelled, and a proper suggestion was not found in the list,
pspell_store_replacement() can be used to store a
replacement pair and then pspell_save_wordlist() to
save the wordlist along with the replacement pairs.
pspell_config_repl() should be used on a config
before calling pspell_new_config().
Parameters
dictionary_link
file
The file should be writable by whoever PHP runs as (e.g. nobody).
