The satpass script provides satellite visibility predictions, given the position of the observer and the NORAD element sets for the desired satellites. It can acquire the NORAD element sets directly from any site supported by Astro::SpaceTrack. It can acquire the observer's latitude and longitude from http://geocoder.us/, look up star positions in the SIMBAD catalog, and more.
This module provides users with Decoder objects for Ogg Vorbis files. One can read data in PCM format from the stream, seek by raw bytes, PCM samples, or time, and gather decoding-specific information not provided by Ogg::Vorbis::Header. Currently, no support for the callback mechanism provided by the Vorbisfile API is supported; this may be included in future releases.
Text::Xslate is a template engine, tuned for persistent applications, safe as an HTML generator, and with rich features. The concept of Xslate is sandboxing. The template logic should have no access outside the template beyond your permission. Templates are compiled into intermediate code and then executed by the virtual machine, which is highly optimized for rendering templates. Xslate supports template cascading, which allows you to extend templates with block modifiers.
XML::RDB is a Perl extension to convert XML files into RDB schemas and populate/unpopulate them. It works with XML schemas too. It analyzes relationships within either an XML file or an XML schema to create RDB tables to hold that document (or any XML document that conforms to the XML schema). It takes an XML file or URL as input for the XML::DOM::Parser, and extracts information to build and write DDL. An attempt is made to recognize relations within the XML structure then translate it to the DDL. That generated DDL is then loaded, parsing the DOM tree a second time to extract and load the data. At the bottom of the DDL are select statements to help get a view of those relations found, and XML data. xml_rdb also dumps the data back to XML format.
FormMagick is a set of Perl modules intended to ease the task of writing multi-page Web forms. It takes a description of the form (fields, validation to perform on each field, etc) in XML format and generates HTML on the fly. Other features include templates for changing the "look and feel" of your forms, and the ability to easily localise your text for other languages.
Proc::Reliable is a Perl module for simple, reliable, and configurable subprocess execution. In particular, it is especially useful for managing the execution of 'problem' programs which are likely to fail, hang, or otherwise behave in an unruly manner. It includes all the functionality of the backticks operator and system() functions, plus many common uses of fork() and exec(), open2() and open3(). It incorporates a number of options, including sending data to the subprocess on STDIN, collecting STDOUT and STDERR separately or together, killing hung processes, timouts, and automatic retries.
