durep creates disk usage reports with bar graphs, allowing one to easily deduce which directories are using the most space.

Although durep can produce text output similar to do, its real power lies in the ability to store reports in a file, which can then be viewed as a web page with the supplied cgi script.

dpkg-du is a quick little script to produce a dump of the installed size of Debian packages in du format. For example, dpkg-du|sort -n|tail -10 will show the 10 biggest packages on your system.

Usage:

Theres no flags. Just dump it in /usr/local/bin or such a place, and run dpkg-du. Enjoy. It should work on any Debian box with awk installed, or any Debian derivative, such as Ubuntu.

PDF::Reuse is a Perl module that can reuse and mass produce PDF documents.

SYNOPSIS

use PDF::Reuse;
prFile(myFile.pdf);
prText(100, 500, Hello World !);
prEnd();

This module could be used when you want to mass produce similar (but not identical) PDF documents and reuse templates, JavaScripts and some other components. It is functional to be fast, and to give your programs capacity to produce many pages per second and very big PDF documents if necessary.

The module produces PDF-1.4 files. Some features of PDF-1.5, like "object streams" and "cross reference streams", are supported, but only at an experimental level. More testing is needed. (If you get problems with a new document from Acrobat 6 or 7, try to save it or recreate it as a PDF-1.4 document first, before using it together with this module.)

Templates

Use your favorite program, probably a commercial visual tool, to produce single PDF-files to be used as templates, and then use this module to mass produce files from them.

(If you want small PDF-files or want special graphics, you can use this module also, but visual tools are often most practical.)

Lists

The module uses "XObjects" extensively. This is a format that makes it possible create big lists, which are compact at the same time.

PDF-operators

The module gives you a good possibility to program at a "low level" with the basic graphic operators of PDF, if that is what you want to do. You can build your own libraries of low level routines, with PDF-directives "controlled" by Perl.

Archive-format

If you want, you get your new documents logged in a format suitable for archiving or transfer.

PDF::Reuse::Tutorial might show you best what you can do with this module.

JavaScript

You can attach JavaScripts to your PDF-files.

You can have libraries of JavaScripts. No cutting or pasting, and those who include the scripts in documents only need to know how to initiate them. (Of course those who write the scripts have to know Acrobat JavaScript well.)

xdiskusage is a user-friendly program to show you what is using up all your disk space.

It is based on the design of xdu written by Phillip C. Dykstra.

Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.

The arrow keys may be used to move the selected directory (shown with a red box) around. There is a pop-up menu (use the right mouse button) with other options for changing the display, you can hide nodes, make that node the "root", change the sort order, etc.

Disc-cover provides an easy way to produce covers for audio CDs. Disc-Cover scans audio CDs and uses information from the CDDB or CDINDEX database to build a back and front cover for the CD. Output is in Latex, Dvi, PDF, Postscript, HTML, plain ASCII, or any other format suited for cdlabelgen.
Main features:
- uses Latex to produce high quality output,
- outputs in Latex, Dvi, Postscript, Pdf, Cddb entry, HTML, ASCII and a format to use with the application cdlabelgen,
- supports caching of cddb entries in a directory that can be shared with other freedb-aware programs,
- connects with a freedb server to get the disc title, artist and list of track titles and extended information where available,
- optionally let Disc-Cover search on allmusic.com for a small version of the corresponding front cover of the cd, which it will put on your front cover,
- optionally put a picture on the front cover, supports almost any image format,
- assign different colours to different items such as artist name and track numbers,
- supports covers for double albums,
- output for jewel cases and various slim cases.

GIMP User Manual project is a user manual for the GIMP. It is written for the GIMP Help Browser, but can produce help pages for other formats as well.
