The Perl HL7 Toolkit provides a simple but flexible Perl toolkit for using the HL7 protocol. The toolkit consists of a Perl API for manipulating HL7 messages, an implementation of a pluggable forking HL7 server for developing HL7 capable applications in Perl, and a queue daemon for polling non-HL7 queues, like database, filesystems, etc., and translating messages in these queues into HL7 (and vice-versa).
ExifTool is a platform-independent Perl library plus a command line application for reading, writing, and editing meta-information in image, audio, and video files. It supports many different types of metadata including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, and ID3, as well as the maker notes of many digital cameras.
libintl-perl is a library that supports message translation for Perl, written in pure Perl (version 5.004 or better). A faster C version is also built and installed if the system fulfills all requirements. Its interface is a superset of the gettext family of functions in C, and it uses the same file formats as GNU gettext, making it possible to use all tools available for gettext itself and to seamlessly integrate internationalized Perl code into mixed-language projects.
PostScript::CDCover generates a Postscript program that prints a CD cover and backlabel, with contents displayed as a tree of directories and files. The module ships with a stand-alone, ready-to-use script, pscdcover, that takes the directory tree of a CD-ROM as input and generates a cover from it. The output can be directly fed to a PostScript printer, but it is designed to be easily editable (should one wish to remove unwanted directory entries, for example).
ZoneMaster is a tool for zone file and name server management. It consists of a library that can configure BIND and a Web-based user interface that is used to access the data that is stored in a database. A bootstrap script allows you to initialize the database with all necessary information retrieved from an existing configuration. All modifications are saved as jobs in the database, and a job handler makes the necessary changes from time to time. The user interface is based on XSLT-stylesheets and can be easily modified.
