	    pdfrack = a hack for using psfrag and pdflatex

**********************************************************************


pdfrack is a  hack designed to  help  the psfrag  users to be  able to
compile their documents with  pdflatex.

It  should not be  considered as   a "solution"  for using  psfrag and
pdftex, but as a "hack" developed for my personal use that can save
your time also.

Please, register yourself by sending me an email with [pdfrack] in the
subject if you  use it. 

Do not hesitate to send me an email to ask for improvements or to
report bugs. I will fix it if I can (but I am not at all a (La)TeX
wizard).

I. What does it do ?
--------------------

The main idea of the script is to scan your source file to find the
figures included (with \includegraphics) and, for each figure, to make
a single latex file with only the figure and to generate a pdf figure
that takes into account the psfrag replacements.

Then, using pdflatex, you just include the pdf figure, with the psfrag
replacements.


II. How to use it ?
-------------------

They are two ways to use it: the lazy automatic one (option -a), where
all figures founds are converted, and the hand-made one, where you
have to select the figures to be converted with the script.

a) Installing it

Put the script pdfrack.sh in a directory included in your path, and
pdfrack.sty somewhere where TeX will find it.

b) Your latex source files

The pictures that you want to translate must be between two lines
\begin{figure}
\end{figure}
and included with command \includegraphics.

If you chose the lazy automatic option, do nothing.

If you chose to select the figures to be translated, just 
 i) include the package pdfrack.sty
 ii) replace \includegraphics by \pdfrackincludegraphics for all the
 figures you want to translate.

c) Running the script pdfrack.sh 

Then, you should run the script pdfrack.sh on your latex source
file. It will generates the figures in pdf format.

It sometimes fails :-( There could be two reasons:
  - the translation from dvi to pdf fails, you should try 
 to put options -p and/or -e, and options -m n, with n in
 0..3 ; but that is not my job :-)
  - the generated latex code is wrong, and this is my fault,
 you can fix the script or email me 

Note that the '%' is is general seen as a comment, even if prefixed
with \. So, avoid to use it.

If your LaTeX code is too complex (if your figures environments are in
included files for  example), then, pdfrack will ne  be able to handle
it. Then,  you should write a  simpler LaTeX file, with your figure(s)
and use this file to generate the pdf figures.

d) Running pdflatex

Then, you could run pdflatex on your file.


III. What is required ?
-----------------------

The pdfrack.sh script uses a lot of other scripts and software.
cut, dvips, epstopdf, grep, head, latex, ps2ps, ps2epsi, sort,
tail, and, first of all, a bourne shell...

Sorry for Win* users. They should install solutions like Cygwin,
or try a Linux distribution.

IV. Why this name ?
-------------------

I think a good solution for using pdflatex and psfrag should be named
"pdfrag" or "pdffrag". I do not think that my solution is good. It is
just a hack. Then pdfrack comes from:
    pdf
  + psfrag
  +    hack
  ---------
    pdfrack

V. How to improve it ?
----------------------

You  can change the   code for your  own purpose,  and email  me your
improvement if you think it could help someone else.

You can ask me some improvements, and I will try to do it.

VI. Why to use it ?
-------------------

They are several other solutions (see the full documentation). This
package tries to be simple. In run only on bash-based systems (Unix,
Linux, MacOS).

VII. Bugs
---------

It seems that there are troubles when using draftcopy and pdfdraftcopy...
