There's no need to install or configure additional drivers or software when deploying.
Zebra_Form is a PHP class that simplifies the process of creating and validating HTML forms. Its object-oriented structure promotes rapid HTML forms development and encourages developers to write clean and easily maintainable code. It frees the developers from the repetitive task of writing the code for validating forms by offering powerful built-in client-side and server-side validation. Zebra_Form has an integrated cross-site scripting prevention mechanism that automatically strips out potentially malicious code from the submitted data. It also prevents automated SPAM posts, out of the box and without relying on CAPTCHA by using honey pots. Output can be generated either automatically or manually through templates (basic PHP files). When generated automatically, the generated output has the same look and feel across all major browsers. It provides all the controls you’d expect in an HTML form and, additionally, date/time pickers, captcha, and AJAX-like file upload controls.

Assimp is a portable and extensible library designed for reading various well-known 3D file formats. It provides APIs for C and C++ and several wrappers for other languages. It reads more than 20 different 3D file formats (including Collada, 3DS, OBJ, LWO, and X) into a straightforward, hierarchical in-memory data structure that can easily be read and processed by applications. Several post processing steps can be applied, such as normal and tangent computations, index buffer, and vertex cache optimization. The library supports complex multi-layer materials and skinned meshes with multiple animations. A Windows-based viewer utility is provided as an implementation reference.
Barcodes for Python is a library that can create EAN-13, Code-128A, Code128-B, Code128-C, and Gs1 barcodes. It also includes a CLI tool that can generate barcode image files and GTK+ and Qt GUI examples with printing support. The barcodes is produces have been verified using a cheap Deltaco (KB Wedge B519153) CCD handheld barcode scanner.
