SYNOPSIS	ptx___ input output
.sp

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", "and", "as",
"is", "for", "of", "on", "or", "the", "to", "up".

The index for this manual was generated using ptx___.
