## What it is
A FontForge Python script that copies Fira Code ligatures into any TrueType or OpenType font, plus pre-ligaturized font releases. It lets developers add programming ligatures to their favorite monospace coding font.

## Use cases
- add ligatures to my favorite coding font
- ligaturize a monospace font with Fira Code glyphs
- get SF Mono with ligatures
- customize which font ligatures are enabled
- batch-convert multiple font weights to include ligatures

## When to choose
- you want ligatures in a font that doesn't ship them
- you prefer your existing monospace font but want Fira Code-style ligatures
- you want pre-built ligaturized versions of popular coding fonts

## When to avoid
- you need ligatures designed natively for your font rather than copied from Fira Code
- you can't install FontForge Python bindings
- you want a GUI tool rather than a script
