ted (Tiny EDitor) is a lightweight commandline text editor designed for scripting. It's intended to be an easier-to-use alternative to "ed". It is lightweight, scriptable, and easily harnessed by shell scripts, but doesn't suffer from the chronic user-unfriendliness that characterizes ed. It is also slightly more featureful than ed, and includes multiple editing buffers and built-in script handling.

ccid-utils is a USB smartcard driver and development platform. The driver follows a simple synchronous design that supports multiple slots but only one transaction at a time and includes a Python interface. It also includes a command line smartcard shell with a searchable history. The shell, written in Python, offers many useful features for developing with smart-cards and for reverse engineering APDU formats. It includes tools for reading data from GSM SIM cards and EMV credit/debit cards. The SIM tool is very basic, but allows reading SMS messages from the SIM. An example EMV (credit/debit) card tool is included that is boilerplate code for utilizing the EMV C API. There is also a Python interface for the EMV API. A graphical interface for reading EMV cards is provided.
debshare.create is a hackish script used for producing .debshare files, which are basically "self-executable", monolithic archives containing several .deb packages. A .debshare file is meant to install one (or more) applications that it contains, complete with all its dependencies. This facilitates easy sharing of applications across computers using a single file, as opposed to multiple .deb packages. This idea was originally meant for Ubuntu systems, but there should be no reason why it shouldn't work on other similar distributions. Technically, a .debshare file is a bash shell script with a binary payload (a tar archive with the .deb-s) appended to it.
