win-bash is port of the GNU bash for Microsoft Windows NT based systems. It is independent from the cygwin library and any other non-standard DLL and does not need any registry variables. win-bash is based on bash_nt from Mountain Math Software. The active development of the project has been discontinued, mainly because of the old age of the code. There are more modern and more bug free alternatives today, which we recommend to use.

The Doszip Commander is an LFN-aware TUI file manager (NC clone) with built-in Zip and UnZip for DOS and Windows.

The Technical Library Template Interface is a library capable of providing standardized interfaces in Creative Commons EAL-4 standards to the open source community.

pdip stands for Programmed Dialogue with Interactive Programs. It is a simplified version of the famous expect utility which interprets a scripting language to dialog with an interactive program as a human operator would do.

FLoM is a free open source distributed lock manager that can be used to synchronize shell commands, scripts and custom developed software. When used in a shell environment, FLoM manages process synchronization in the same way that "nice" manages process prioritization. Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication.
