This is the GNU C compiler, a fairly portable optimizing compiler for C.

Library for macromolecular crystallography and structural bioinformatics. For working with coordinate files (mmCIF, PDB, mmJSON), refinement restraints (monomer library), electron density maps (CCP4), and crystallographic reflection data (MTZ, SF-mmCIF). It understands crystallographic symmetries, it knows how to switch between the real and reciprocal space and it can do a few other things.

LLVM is a collection of libraries and tools that make it easy to build compilers, optimizers, just-in-time code generators, and many other compiler-related programs.

This package installs the required files for reading JPEG XL files in GTK applications.

The JPEG XL Image Coding System (ISO/IEC 18181) is a lossy and lossless image compression format. It has a rich feature set and is particularly optimized for responsive web environments, so that content renders well on a wide range of devices. Moreover, it includes several features that help transition from the legacy JPEG format.
