Options.pm is a command-line option-parsing Perl module meant to imitate the syntax of the t.p.usage.Options module from the Twisted Python library. It will allow you to specify which options to look for on the command line, and supports both long and short versions of simple flags and parameters. If a required parameter is unspecified, Options.pm will print nicely formatted usage information with the error.
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).
XML::Parser is a Perl extension module providing an interface to James Clark's fast and robust XML parsing library, expat. Other Perl XML modules (many based on XML::Parser) may be found at the same CPAN download site where XML::Parser is located. The expat library is distributed as part of the module.
Sql2xml is a CGI program that lets you request a SQL query and convert it to JSON, CSV, XML or INI through a Web server. Sql2xml supports requests from multiple users and for multiple databases. It is intended for developers who do not have direct access to database servers due to firewalls or other restrictions.
Monotone::AutomateStdio is a Perl library module for accessing Monotone's automate stdio interface. Monotone is a distributed, change-set based SCM system. It has a mode where commands can be sent to it via STDIN and output read from it via STDOUT. Monontone::AutomateStdio makes use of this facility to provide the Perl programmer with a programmatic interface to Monotone.
The CentralNic Toolkit is CentralNic's system for instantaneous Registry-Registrar Communications. Registrars can use this system to register and modify CentralNic domain names in real time, with no delays for human intervention or e-mail processing. The Toolkit also provides advanced and efficient methods for searching for and querying domain names and whois records, and retrieving account information.
qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core SMTP features, all functionality is implemented in small "extension plugins" using the easy-to-use object oriented plugin API. qpsmtpd was originally written as a drop-in qmail-smtpd replacement, but now it also includes an smtp forward and a postfix "backend".
