OmegaT is a translation memory application intended for professional translators. It does not translate for you (software that does this is called "machine translation"). It features fuzzy matching, match propagation, simultaneous processing of multiple-file projects, simultaneous use of multiple translation memories, and external glossaries. Document file formats include plain text, HTML, and OpenOffice.org/StarOffice. It has Unicode (UTF-8) support (can be used with non-Latin alphabets). It is compatible with other translation memory applications (TMX Level 1).
JRequisite is an agile requirement management tool, which means your requirements are defined mainly via visual tools as opposed to textual requirement tools. Also, it is independent of the process used, so you may apply any process to your development. Despite being a requirement analysis and management tool, JRequisite tools are so general that they can be used in other areas of software development and even non-software related fields.
PHK is a library and application packager. It is a sort of PHP-oriented jar. As such, it allows you to distribute and run a whole application as a single file.
