WP2LaTeX is a program designed to translate WordPerfect documents into LaTeX 2.09 and LaTeX 2.0e. It is able to cope with Macintosh WordPerfect 1.x, 2.x, 3.x, and 4.x and PC WP 4.x, 5.x, and 6.x documents (WP 7.x and 8.x have same binary file format as 6.x, so no additional conversion module is necessary.)
stdnoj is a cross-platform C++ class library that includes classes for using portable strings, databases, SMTP, POP, NNTP, arrays, files, directories, logging, email, and sockets. While templates are used, no reliance upon STL or other (traditionally error-prone) technologies has been used, which increases portability between compilers.
MailListStat is a tool that generates useful statistics for email archives stored in the mbox format. It will show the top 10 authors, most successful subjects, and more. It also prints graphs showing the number of messages written during different hours of the day, days of the month, and days of the week. The output is in text format suitable for mailing. It also produces output in plain text or HTML format, includes a PHP wrapper, and supports cache files. It is mainly useful for mailing list archives, producing tables and graphs, and supporting different output languages.
