[Techtalk] editing a .ps or .pdf

[k]

A little late, but, hi,

In that case, the author kindly made available the "source code" of
this PDF, as you can find at the root directory
(http://www.nmt.edu/~val/review/hash2.tar.gz), specially for your
editing needs.

As you can see, this document was not edited directly in PDF format,
but in TeX. Usually, PDF is an output format, and the original
document was created in something else than Adobe's proprietary
editor.

Therefore, you can easily edit this PDF by editing the TeX source code
with any some editor (Emacs has a built-in mode for TeX documents),
and running "pdflatex" on it.

I highly recommend trying it, instead of using some WYSIWYG PDF
editor, as TeX, and specificaly LaTeX is a relatively easy markup
(typesetting) language for documents such as articles and books, that
makes the creation of professional, academic, and good looking
documents in general a very easy task. And virtually all Linux
distributions include the "tetex" package for doing so, but it is
usually overlooked...

bye,
