excat is a simple tool that auto-detectd (potentially nested) compressed file formats and decompresses any combination of them using libarchive, thus unifying zcat, bzcat, lzcat, xzcat, etc. in a single (static, if you need it) binary. It may act as a drop-in replacement for any *cat.
FontMapper is a font texture generator for game developers. It allows you to turn a font you have installed to a PNG texture of tightly packed glyphs, accompanied by a text file describing the glyphs' properties and texture coordinates. You can read these in a game to render fonts. FontMapper supports Unicode (although only the Basic Multilingual Plane, i.e. the 16-bit codepoints), and each glyph can have its own size, i.e. fonts are not necessarily monospaced. Currently, FontMapper is command-line only, although there might be a GUI frontend in the future.
pyautomate is a general-purpose CLI automation tool. Unlike other tools, you describe a state machine in a configuration file and use the CLI to go to a certain state. pyautomate will automatically figure out which tasks to run to get to your desired state. The configuration file is a Python 3 module, which allows you to easily and flexibly define your tasks.
