CsvMail is an HTML form mailer and manager. It mails the results of form submissions and also writes the entry to a secure.csv file. It requires minimal HTML form changes - just change the beginning form tag to post to CsvMail. It is very easy to configure, but includes plenty of extra options, including domain security settings and a bounceback required fields option. A fully-functional evaluation version is available.
There are many photo-gallery programs available. Zoph is different, as it concentrates on the management of large collection of photos instead of just showing them on the Web. It can store a lot of information about your photos, including the regular EXIF info, photographer, location, title, description, rating, and the people in the photo. Photos can appear in multiple albums and categories. Additional features include search, slideshows, lightboxes, email, access privileges, and multiple languages.
The par utility creates and manipulates PalmOS database (.pdb) and resource (.prc) files. Par is designed to be a Swiss army knife for managing these files. It's a command line tool, and not for the faint of heart, but it's very handy and replaces a bunch of little utilities that you might otherwise use.
