Tweeter is another command line script that can update your Twitter status from the command line. It also uses the SSL link to protect your username and password. Tweeter can only post a new status; it cannot follow anyhone, send direct messages, or anything else. The username and password are not stored on the file system, so you can post to different accounts with ease. It should also work on older machines.
PlainDoc is a document production system based on plain text files. It keeps most of the document in human readable form; the PlainDoc source itself serves as the plain text version of the document. It handles EPS, gnuplot, dia diagrams, tables, and verbatim text, uses LaTeX for PDF production, and can produce monolithic or paginated HTML and DocBook natively. Includes are supported. The file format is CVS friendly and easily diffable. It is suitable for software manuals and documentation, technical publishing, scientific papers, books, legal documents, and presentation slides.
