It has three phases: the first does the permutation, generating one line for each keyword in an input line. The keyword is rotated to the front. The permuted file is then sorted. Finally the sorted lines are rotated so the keyword comes at the middle of the page. input_____ should be edited to remove useless lines. The following words are suppressed: "a", "and", "as", "is", "for", "of", "on", "or", "the", "to", "up". The index for this manual was generated using ptx___. .sp .ti 0 FILES -- .sp .ti 0 SEE ALSO sort(I) .sp .ti 0 DIAGNOSTICS some .sp .ti 0 BUGS --
