Tk is a graphical toolkit for building graphical user interfaces (GUIs) in the Tcl language.

Tcllib, the standard Tcl library, is a collection of common utility functions and modules all written in high-level Tcl.

Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, etc. Expect really makes this stuff trivial. Expect is also useful for testing these same applications. And by adding Tk, you can wrap interactive applications in X11 GUIs.

[incr Tcl] is a widely used object-oriented system for Tcl. The name is a play on C++, and [incr Tcl] provides a similar object model, including multiple inheritance and public and private classes and variables.

Extended Tcl is oriented towards system programming tasks and large application development. TclX provides additional interfaces to the operating system, and adds many new programming constructs, text manipulation tools, and debugging tools.

The Tcl (Tool Command Language) scripting language.

TclXML provides event-based parsing of XML documents. The application may register callback scripts for certain document features, and when the parser encounters those features while parsing the document the callback is evaluated.

This extension provides a generic binding to OpenSSL, utilizing the Tcl_StackChannel API for Tcl 8.2 and higher. The sockets behave exactly the same as channels created using Tcl's built-in socket command with additional options for controlling the SSL session.

This program converts Telegram's animated stickers in TGS format into a series of PNG images.

TG is the command-line interface for Telegram Messenger.

TGL is the telegram library for telegram-cli.

TgCli is a telegram client to automate repetitive tasks.

WebRTC-for-Telegram-Desktop is a custom WebRTC fork by Telegram project, for its use in telegram desktop client.

Tdlib is a cross-platform library for creating custom Telegram clients following the official Telegram API. It can be easily used from almost any programming language with a C-FFI and features first-class support for high performance Telegram Bot creation.

Telegram desktop is the official desktop version of the Telegram instant messenger.

TL-Parser is a tl scheme to tlo file parser. It was formerly a part of telegram-cli, but now being maintained separately.

This package provides an implementation of the Secure Real-time Transport Protocol (SRTP), the Universal Security Transform (UST), and a supporting cryptographic kernel.

Mumble is an low-latency, high quality voice chat software primarily intended for use while gaming. Mumble consists of two applications for separate usage: mumble for the client, and murmur for the server.

LibIAX2 implements the Inter-Asterisk-Protocol for relaying Voice-over-IP (VoIP) communications.

Libosmocore includes several libraries:

• libosmocore: general-purpose functions

PJProject provides an implementation of the Session Initiation Protocol (SIP) and a multimedia framework.

PJProject provides an implementation of the Session Initiation Protocol (SIP) and a multimedia framework.

GNU ccRTP is an implementation of RTP, the real-time transport protocol from the IETF. It is suitable both for high capacity servers and personal client applications. It is flexible in its design, allowing it to function as a framework for the framework, rather than just being a packet-manipulation library.
