The PCI Utilities are a collection of programs for inspecting and manipulating configuration of PCI devices, all based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems. This includes the lspci and setpci commands.

hwdata contains various hardware identification and configuration data, such as the pci.ids and usb.ids databases. Each database is contained in a specific package output, such as the pci output for pci.ids, the usb output for usb.ids, etc.

The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE has its own native API, as well as a set of wrapper functions that correspond to the POSIX regular expression API.

PDFmarks is a technique that accompanies PDF, and that is used to store metadata such as author or title, but also structural information such as bookmarks or hyperlinks.

When Ghostscript reads the main PDF generated by the TeX system with embedded PDF files and outputs the final PDF, the PDF page mode and name targets etc. are not preserved. Therefore, when you open the final PDF, it is not displayed correctly. Also, remote PDF links do not work correctly.

This program is able to extract the page mode and named targets as PDFmark from PDF. In this way, you can obtain embedded PDF files that have kept this information.

Xournal++ is a hand note taking software written in C++ with the target of flexibility, functionality and speed. Stroke recognizer and other parts are based on Xournal code.

Stapler is a pure Python alternative to PDFtk, a tool for manipulating PDF documents from the command line. It supports

• cherry-picking pages and concatenating them into a new file

• splitting a PDF document into single pages each in its own file

• merging PDF documents with their pages interleaved

• displaying metadata in a PDF document

• displaying the mapping between logical and physical page numbers

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains only the command line tool. If you like to use the gui, please install the flyer-composer-gui package.

The cpdf package provides a command-line tool and an OCaml library designed for manipulating PDF documents. Key Features include:

• Splitting and merging PDF files (including bookmark preservation and splitting on bookmarks).

• Encryption and decryption (supports AES 128 and AES 256).

• Page manipulation: scaling, rotation, cropping, and flipping; fitting pages to a specific size.

• Bookmark management: copying, removing, and adding bookmarks.

• Watermarking: stamping logos, page numbers, and multi-line text with transparency support.

• Text and font handling: embedding TrueType fonts, supporting Unicode UTF-8 input and output, and converting text to PDF.

• Presentation features: creating PDF-based presentations and arranging multiple pages on a single page.

• Annotation management: listing, copying, setting, and removing annotations.

• Metadata management: reading and setting document information and metadata.

• Attachment handling: adding and removing file attachments to documents or pages.

• Advanced features: thickening hairlines, blackening text, reconstructing malformed files, detecting missing fonts and low-resolution images, exporting/importing in JSON format, and building table of contents.
