NAME
ptx - permuted index
SYNOPSIS
ptx [ -t ] input [ output ]
DESCRIPTION
Ptx generates a permuted index from file input on file
output. 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', `an', `and', `as',
`is', `for', `of', `on', `or', `the', `to', `up'.
The optional argument -t causes ptx to prepare its output
for the phototypesetter.
The index for this manual was generated using ptx.
