pdfconcat
---------

This program concatenates PDF files and optionally converts text
within them into bitmaps. The concatenation is done with Ghostscript (gs);
the detextification is done with a gs-conversion to tiff and tiff2pdf
(package libtiff-tools) afterwards. Detextification is only in gray-scale.


Contents:

- bin/pdfconcat		shell script to concatenate PDF files
- bin/pdfdetextify	shell script to convert text to images in PDF files
- pdfconcat.php		web interface to invoke the scripts

- log			log file of web interface invocations (writable)
- bin/monthly		shell script to sum up the usage by month

- upload/		directory to store the converted files (writable)
- bin/cleanup.cron	helper script to remove old uploaded files

- .user.ini		php config file to increase the max upload file size


Installation:

You need a Unix system. Ensure you have gs and tiff2pdf (in the package
libtiff-tools) available.

To use the bin/pdf* tools on the command line only, copy them to your $PATH
and make them executable.

To set up the program including the web interface, copy the files to a place
below the webserver root. Make bin/pdf{concat,detextify} executable for
www-data. Make the log and the upload directory writable by www-data. Install
a cronjob to clean up the upload directory. Ensure that the max upload file
size of PHP is large enough.
