Native implementation of Godot Xterm using GDNative with [libtsm](https://github.com/Aetf/libtsm). Native implementation of Godot Xterm using GDNative with [libtsm](https://github.com/Aetf/libtsm).
Terminal emulator for Godot using GDNative and [libtsm](https://github.com/Aetf/libtsm).
**Note**: If you are looking for the purely gdscript version of this plugin it was too buggy and slow so is no longer being developed or maintained but can found [here](https://github.com/lihop/godot-xterm/tree/gdscript-unmaintained).

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------
PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

# godot -s -d test/gut/gut_cmdln.gd

# See the readme for a list of options and examples. You can also use the -gh

# godot -s -d test/gut/gut_cmdln.gd
