lwmenu is a TCL/Tk program that displays an application menu at the current X pointer position. It was written in order to scratch an itch--namely that lwm (Lightweight Window Manager) does not have a built-in application menu. It can be also used for other window managers that either don't have their own application menu (such as lwm) or don't currently have a menu-method written for the Debian menu system.
YaaCs (Yet Another Advanced Cati system) is written in Tcl/Tk to manage and realize computer assisted telephone interviewing (CATI) and telemarketing. It make easy monitoring survey progress (giving several information), and it allows the management of the the survey with several administration tools. It simplifies the interviewer's work reading all contact's data from an easy and functional GUI. It can send faxes via hylaFAX and save all contact's data in a PostgreSQL database.
