To process a document with the spell checker, use sphinx-build and specify spelling as the builder name using the -b option. The output includes the headings from the document and any misspelled words. If suggestions are enabled, they are shown on the same line as the misspelling. A log of the words in each input file not found in the dictionary is saved to the file <input>.spelling under the build directory.
