glsltc is the default compiler front-end for the GLSLT language. To use the GLSLT transforms from Rust or Python code, see the documentation for the glslt crate.

Extract the pre-built binary for your platform from the releases somewhere in your $PATH.

Alternatively, you may compile GLSLT from source and install it using cargo install --force .
