Saswire is a Perl program which generates a database in SDBM format containing the modification time, MD5 checksum, size, and creation time for a list of files specified in a input file. It is designed to check for unwanted modifications of Unix system binaries if security is compromised.
I/O Fender provides a simple and efficient binary buffer interface that is independent of the backstore used. The interface is much like the traditional file access interface; iofender buffers expand as needed, and an offset is kept for determining where in the buffer operations are applied.
PTML is a Python module which lets you embed Python code in text documents. Its most common application is dynamic content generation on Web servers, but it can be used anywhere you need to generate text files on-the-fly. The project is still at a very early stage, although the code should be usable enough for you to learn the syntax and experiment with possible applications. Future directions are briefly listed in the TODO file; suggestions and contributions are most welcome.
