It has a clean, portable, object oriented pure Perl API without any hidden magic and no requirements besides modern Perl, but can use many CPAN packages out of the box. It has a HTTP 1.1 and WebSocket client/server implementation with TLS, IDNA, Comet (long polling), chunking, and multipart support, and an async I/O Web server supporting EV pluggable event queue, Unix domain sockets, and hot deployment. Automatic CGI, FastCGI, and PSGI detection allows for any deployment situation. It has a JSON and XML/HTML5 parser/emitter with an advanced CSS3 selector support and DOM.

Aspose.Cells for Reporting Services allows you to export native Excel reports in Microsoft SQL Server 2005 Reporting Services. Unlike the built-in renderer for Excel based reports, Aspose.Cells for Reporting Services provides an extended feature set and allows RDL reports to be converted to: Excel 97-2003 binary XLS format, SpreadsheetML, or the Excel2007 XLSX format. With the Aspose.Cells Report Designer tool, users can design and deliver reports into MS Excel directly without using Visual Studio IDE.
Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. It runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems, and should run on pretty much any system with a decent C++ compiler. Xpdf is designed to be small and efficient. It can use Type 1 and TrueType fonts.
